If those files go missing then the game is going to generate new land where you are. Catch the error and provide a useful error message if this happens. Aside: My initial impressions are 4. Have a question about this project? Having looked at a couple of options I settled on that one too. In particular, command lines should continue to run without any changes. For this particular problem, there are. This was also causing an ugly stack trace on stop with Java 9 as it tried to find a logging configuration to use.

Error: Unresolved compilation problems: The import pwsz. Why does it need access to this strange isTransient? But sometimes, when testing, I need access to features and functionality that, for seemingly arbitrary reasons, the class does not support. There are other options if you don't mind changing config to switch between versions. I haven't checked performance either. So from Java 9 on, the system property java. I do like the reduction in code and the build script complexity doesn't concern me overly - it is mostly adding volume rather than an complex logic.

This started to fail on Java 1. Which may sound very fortunate, is the opposite if you mix in the class loading behavior: If a package is split between a module and the class path, for classes from that package class loading will always and only look into the module.

The java option -- add - opens uses the same syntax as -- add - exports and opens the package to deep reflection, meaning all of its types and their members are accessible regardless of their visibility modifiers.

Particularly deny is very helpful to hunt down reflective access. Now, in the case of split packages, this means a split between a named module e.

Unfortunately it has been added with package visibility. For the JreCompat code, we would need this. People can do this in their own code, but a library you import should never-ever do this by default! Error: Unresolved compilation problems: The import pwsz. If you indeed just have a couple of classes that split a package, the long-term solution is to remove the split. Server - create a domain in an empty directory and start the server java weblogic. Also note that while you need to know a bit about , this is not about modularizing your application — it is only about getting it to compile and run on Java 9. Knowing how to fix these will give you very good chances to overcome all your migration challenges and make your application compile and run on Java 9.

Going Further Finding split package by try and error is pretty unnerving. Its a side effect of Java's security model for method handle lookups. Indeed, I ran my first multi-release Jar experiment successfully today. To display the auto-configuration report re-run your application with 'debug' enabled. I haven't shared them and now I go back to re-read them my notes are somewhat disorganized.

I'm working with the latest 4. As I said server info is my weak point. Error: Unresolved compilation problems: The import pwsz. I've added to the list of J9 back-port candidates. If we would use it like that, we would have to slightly reorganize our svn layout to reflect that, e. I guess I'm +0 on switching at this point. When googling further, we might find the following solution, which accesses internals through reflection: import java.

I marked the ones where I found the revision in the 8. Here is Groovy's example: To make the test also run with Java 8, I'd do it in a similar way. As 1 and 2 are not much of a problem, I have not pursued this idea yet. Then, it must have access to all the dependencies that it needs to run successfully. And I agree we need to make it as a configurable option, but to cover most of the real life scenarios it is going to be on by default.

During a migration to Java 9, you will always use that placeholder. I've copied the list to the wiki so it can be updated as progress is made. You should instead consider creating a new class loader for that. I've put together a list of the Java 9 commits that need to be back-ported. Recommendation: Check the Supported System Configurations Guide for further details.

But I could not actually find that point. If so, your chances to do a migration with only small changes are slim.

You can then write: Reflect. It is possible to change it to be as simple as Changeset looks fine, although I have no idea how the extra test should pass on Java 8. I should not be accessing its private fields and methods. In case that is not possible in the short-term, you can patch the named module with the content from the class path. Error: Unresolved compilation problems: The import pwsz. I've added to the list of J9 back-port candidates.
