UnsupportedClassVersionError: STGeomFromText has been compiled by a more recent version of the Java Runtime about dremio-udf-gis

Thanks for reverting Idan. I don't know how starring slipped out of my mind after creating the issue, I was up to starring and I have already.

You answered my query in full, Thanks!

Hi.

Thank you for the warm words (starring == caring)
For your issue - Dremio 20.x now supports JDK 11, and this code is compiled for JDK11.
I'd strongly recommend migrating your installation to JDK 11, which can now use more advanced GC as part of the mainline build (Shenandoah/ZGC) (starting from 11.0.9).

I'll perhaps add JDK8 build target in an upcoming release. If you can't migrate to JDK11 and must use a JDK8 build, let me know and I'll help you out 😄

As for more usage samples - for now, you can follow Drill for usage direcative.
But you are correct, I'll add more sample to this GH project soon.

@jaysnm It seems that dremio OSS cannot be compiled in JDK 11. Is there any relevant document to share?
thank you

@bigfacewo please open a separate issue describing your errors in detail, 10x

Hello @bigfacewo

I did not compile dremio from source but rather used already compiled archives from dremio download server. Perhaps you may want to create a new issue for this!

[bigfacewo]

@jaysnm "Dremio community" 20.1 should be compiled in "JDK1.8" or "jdk1.9". This is the definition of JDK version in Maven:https://github.com/dremio/dremio-oss/blob/31bc9b7ce0aa88ac2ab8ebcbc9fb69fb0d2744a8/pom.xml#L524

I tried to modify the definition and compile using jdk11, but it didn't succeed, so I want to know, even if dremio uses jdk1.8 compilation, can it also run in JDK 11? I don't know this very well.

[jaysnm]

I downloaded this tar ball and it just works fine with jdk11. My be I am doing something wrong but it works!

[bigfacewo]

@jaysnm Thank you for telling me that.
