Greetings,

this enhancement adds a "source" field, label "Location" to the jdk.ClassDefine event.

To enable this functionality, JFR needs a concurrent symbol table. We can build a simpler version of a concurrent hash table, taking advantage of the JFR epoch system. This will be useful also for planned future enhancements.

Extensions are made to AOT to consistently report identical canonical paths for classes as non-AOT code paths.

Testing: jdk_jfr, manual AOT verification, stress testing

Thanks Markus
