Invalid kulla.jar?

[donghanglin]

kulla.jar downloaded from the link on README seems not compatible with the newest jdk b99.

It took me hours to figure out why my installation failed. After I redownloaded the kulla.jar from this link, the installation finally succeed.

[Bachmann1234]

@donghanglin oh jeez. I had not realized that this had gotten out of date. Sorry for the trouble, Thanks for the heads up. Ill give it a shot and update the readme soon.

Super handy link as well :-)

[Bachmann1234]

I had trouble reproducing this. Can you let me know the error?

I am going to update the readme anyway because your link seems better than what I got there anyway and I tested the jar from there

I use jdk-9 b99. When working with the former kulla.jar, Exception will raise after executing java -jar kulla.jar

Exception in thread "main" java.lang.UnsupportedOperationException: Wrong compiler, must be run with full JDK 9.

If run ipython console --kernel java, the output error is:

When working with the updated kulla.jar, all errors were gone.

Weird.

So this is what happens when I try both jars (I also include my java --version output)

But no biggie, Your link is clearly more correct. I already updated the readme pointing to it. Think this issue is ready to close?

[donghanglin]

Yeah, it's weird. Close it.
