Closed volyx closed 4 years ago

volyx commented 4 years ago

GraalVM is not supported.

GraalVM version - 19.2.0 mapdb-3.0.8.

Error: com.oracle.svm.hosted.substitute.DeletedElementException: Unsupported type java.lang.invoke.MemberName is reachable: All methods from java.lang.invoke should have been replaced during image building.
To diagnose the issue, you can add the option --report-unsupported-elements-at-runtime. The unsupported element is then reported at run time when it is accessed the first time.

Cleaner hack will be made optional in MapDB4. GrallVM is not right now supported, but I am thinking about it.
