Java runtime not eligible

[FIXED] — Java Runtime error

includes evaluation version of Java Runtime not eligible for distribution.

Do i have to do something to solve this ?

That would be awesome to know as I got the same problem as of today.

Same here, isn’t the App supposed to be rewritten in Kotlin ( so no more Java ) ?

Same thing since this morning

Indeed cant launch program with out this error. Java does it again!

Today i had an error launching PAL2:

includes evaluation version of Java Runtime not eligible for distribution.

Do i have to do something to solve this ?

No, from the error message it seems like the new update was wrongly deployed somehow.

Oracle has changed the Java licenses for 2019, and most updates for Java 8 (which it seems this addon runs on) which will require a fee to distribute. However this project should be non-commercial, so the java distributed runtime probably just needs updating to work again, since the license fees do not apply for these.

@Pekno Kotlin is also a JVM language which means that its requires a Java runtime environment (JRE) to run.

Is there any idea for an ETA on the updated version which works?

same problem there fix this!

While we wait for a updated release I thought this might help some folks who want to still run their addons that are usually managed by PAL2.

PAL2 has most of the addons in one of two locations. You must have Windows show «hidden folders» or go to your search bar (usually next to the «start» button/logo in the bottom left hand corner of your screen) and type %appdata% and press enter. Then proceed to navigate to:

Obviously, «yourfolder» above is going to be different for each computer and the user account setup on it that you are logged into.

Now just go to each of the Addon folders and look for their shortcut to manually start the program/script.

Update coming in a few minutes, gonna repack and then it will break again in 90 days, I’ve e-mailed Excelsior JET to get a possible Free License so that it won’t happen again, sorry for the inconvience!

NOTE:
You’ll have to manually update to v1.0.8
This means replacing all of the files where you installed it.

Java Runtime not eligible for distribution

I am getting this weird error when trying to run my Java program that I created as well as Jet Control Panel and JetPack 2. I have tried to run it on different computers with the same result.

Best Solution

In the manual page on configuring the JET Runtime, there is a section about system files shipped with JetPackII, which tells you that JET includes its own copy of the Java runtime libraries.

The error message is telling you that the Java Runtime that is packaged with JET is an expired evaluation version. That indicates that your version of JET is an evaluation version that has expired.

There are several ways to solve this error:

• Pay the licensing fee
• Get a free license for non-commercial use
• Try to install another 90-day evaluation copy
• Find another way to package your software

Java – Is Java “pass-by-reference” or “pass-by-value”

Java is always pass-by-value. Unfortunately, when we deal with objects we are really dealing with object-handles called references which are passed-by-value as well. This terminology and semantics easily confuse many beginners.

public static void main(String[] args) < Dog aDog = new Dog("Max"); Dog oldDog = aDog; // we pass the object to foo foo(aDog); // aDog variable is still pointing to the "Max" dog when foo(. ) returns aDog.getName().equals("Max"); // true aDog.getName().equals("Fifi"); // false aDog == oldDog; // true >public static void foo(Dog d) < d.getName().equals("Max"); // true // change d inside of foo() to point to a new Dog instance "Fifi" d = new Dog("Fifi"); d.getName().equals("Fifi"); // true >

In the example above aDog.getName() will still return «Max» . The value aDog within main is not changed in the function foo with the Dog «Fifi» as the object reference is passed by value. If it were passed by reference, then the aDog.getName() in main would return «Fifi» after the call to foo .

public static void main(String[] args) < Dog aDog = new Dog("Max"); Dog oldDog = aDog; foo(aDog); // when foo(. ) returns, the name of the dog has been changed to "Fifi" aDog.getName().equals("Fifi"); // true // but it is still the same dog: aDog == oldDog; // true >public static void foo(Dog d) < d.getName().equals("Max"); // true // this changes the name of d to be "Fifi" d.setName("Fifi"); >

In the above example, Fifi is the dog’s name after call to foo(aDog) because the object’s name was set inside of foo(. ) . Any operations that foo performs on d are such that, for all practical purposes, they are performed on aDog , but it is not possible to change the value of the variable aDog itself.

For more information on pass by reference and pass by value, consult the following SO answer: https://stackoverflow.com/a/430958/6005228. This explains more thoroughly the semantics and history behind the two and also explains why Java and many other modern languages appear to do both in certain cases.

Java – Avoiding NullPointerException in Java

This to me sounds like a reasonably common problem that junior to intermediate developers tend to face at some point: they either don’t know or don’t trust the contracts they are participating in and defensively overcheck for nulls. Additionally, when writing their own code, they tend to rely on returning nulls to indicate something thus requiring the caller to check for nulls.

To put this another way, there are two instances where null checking comes up:

1. Where null is a valid response in terms of the contract; and
2. Where it isn’t a valid response.

(2) is easy. Either use assert statements (assertions) or allow failure (for example, NullPointerException). Assertions are a highly-underused Java feature that was added in 1.4. The syntax is:

where is a boolean expression and is an object whose toString() method’s output will be included in the error.

An assert statement throws an Error ( AssertionError ) if the condition is not true. By default, Java ignores assertions. You can enable assertions by passing the option -ea to the JVM. You can enable and disable assertions for individual classes and packages. This means that you can validate code with the assertions while developing and testing, and disable them in a production environment, although my testing has shown next to no performance impact from assertions.

Not using assertions in this case is OK because the code will just fail, which is what will happen if you use assertions. The only difference is that with assertions it might happen sooner, in a more-meaningful way and possibly with extra information, which may help you to figure out why it happened if you weren’t expecting it.

(1) is a little harder. If you have no control over the code you’re calling then you’re stuck. If null is a valid response, you have to check for it.

If it’s code that you do control, however (and this is often the case), then it’s a different story. Avoid using nulls as a response. With methods that return collections, it’s easy: return empty collections (or arrays) instead of nulls pretty much all the time.

With non-collections it might be harder. Consider this as an example: if you have these interfaces:

public interface Action < void doSomething(); >public interface Parser

where Parser takes raw user input and finds something to do, perhaps if you’re implementing a command line interface for something. Now you might make the contract that it returns null if there’s no appropriate action. That leads the null checking you’re talking about.

An alternative solution is to never return null and instead use the Null Object pattern:

public class MyParser implements Parser < private static Action DO_NOTHING = new Action() < public void doSomething() < /* do nothing */ >>; public Action findAction(String userInput) < // . if ( /* we can't find any actions */ ) < return DO_NOTHING; >> > 

Parser parser = ParserFactory.getParser(); if (parser == null) < // now what? // this would be an example of where null isn't (or shouldn't be) a valid response >Action action = parser.findAction(someInput); if (action == null) < // do nothing >else

ParserFactory.getParser().findAction(someInput).doSomething(); 

which is a much better design because it leads to more concise code.

That said, perhaps it is entirely appropriate for the findAction() method to throw an Exception with a meaningful error message — especially in this case where you are relying on user input. It would be much better for the findAction method to throw an Exception than for the calling method to blow up with a simple NullPointerException with no explanation.

try < ParserFactory.getParser().findAction(someInput).doSomething(); >catch(ActionNotFoundException anfe)

Or if you think the try/catch mechanism is too ugly, rather than Do Nothing your default action should provide feedback to the user.

public Action findAction(final String userInput) < /* Code to return requested Action if found */ return new Action() < public void doSomething() < userConsole.err("Action not found: " + userInput); >> >

the error message telling java runtime packaged jet expired evaluation version. indicates version of jet evaluation version has expired.

there several ways solve error:
