Koloboke Fails to Compile on Java 9

[danthonywalker]

When compiling a project that has previously compiled correctly on Java 8 using Java 9, this exception appears.

Error:(42, 17) java: Koloboke Compile annotation processor threw an exception while processing this type,

I second this. Do you have plans to support JDK 9 in the future? Thanks for this great project btw!

[leventov]

I started works towards open-sourcing Koloboke Compile some time ago. Not sure if I will make it work with Java 9 but at least you will be able to hack on this project.

[drivenbyentropy]

Thanks for the update.

For now, I have worked around the issue with the following hack. I used Koloboke Compile to generate an implementation for my data structure. I then took the hardcoded version from the generated sources folder and replaced the abstract class with it. Not pretty, but it works and compiles just fine with Java 9.

I will be looking out for updates on open-sourcing Koloboke Compile 👍

@leventov were you able to make any progress towards open sourcing Koloboke Compile? Would be interested in making it run on Java >8. The library has been great to work with so far, but we recently moved up in JDKs and now I'm following the same pattern ^

[leventov]

I would like to open-source Koloboke Compile, but I'm not sure it will ever happen. If I were you, I would not count on this.
