Esper 8.8.0/8.9.0 not compatible with hibernate 6.*.*

[bernhardttom]

ANTLR has information on this issue here: antlr/antlr4#3895
The script that regenerates the parser can be found in esper\compiler\grammar
We don't have a date yet when the new version ships, but it would probably ship with the current 4.13.x version of ANTLR.

Is there an exception when forcing the new ANTLR version?

[Prashant8976]

Hibernate 6.. adds Antlr-runtime 4.10.1 jar, So esper gives following error

Antlr tool version 4.9.3 used for code
generation does not match with current
runtime version 4.10.1
Antlr tool version 4.9.3 used for parser
compilation does not match with current
runtime version 4.10.1 Java.io.invalidclassexception:org.antlr.v4.runtime.ATN; could not deserialize ATN with version 4(expected 3)

If antlr-runtime 4.9.3 is used, after excluding it from hibernate, jpa annotations doesnt work, it gives following error-

Antlr tool version 4.10.1 used
generation does not match with current
runtime version 4.9.3
Antlr tool version 4.10.1 used for parser
compilation does not match with current
runtime version 4.9.3

This also means that esper is incompatible with Spring boot 3, since it uses hibernate 6, which is a critical issue on our project which needs to be migrated urgently to spring boot 3 but it's blocked by esper.

Would be really good to get an update with the new ANTLR version soon. All newer Spring boot versions that still have OSS support require builds with the new ANTL to be compatible.

Changes are in version 9.0.0
