Verify library is JDK11 compatible

[AlexeyRedinskii]

The library uses some byte code manipulation tools that may not be compatible with JDK11.

Indeed there is asm dependency (which is not used). What tool gives this compat-related information ?

[AlexeyRedinskii]

@lopex it's an internal tools that we use to migrate to JDK11. If asm is not used, maybe you can release a new version without that dependency?
Thank you!

[AlexeyRedinskii]

@lopex hello! How do you think, is this going to happen any time soon? Otherwise we would have to move away to a different library. We must move to JDK11 asap.

asm dep is removed and new joni is released, waiting for sonatype to propagate.
