8316271: JfrJvmtiAgent::retransformClasses failed: JVMTI_ERROR_FAILS_VERIFICATION #16379

@mgronlun mgronlun commented Oct 26, 2023


sometimes when running JFR with -Xverify:all, the bytecode retransform would fail with an JVMTI_ERROR_FAILS_VERIFICATION.

I say sometimes because it depends on whether event classes located in java.base are loaded before JFR is started.

If so, for those event classes, the type of the static field eventConfiguration is untyped, i.e. java.lang.Object, because the java.base module cannot use types in module jdk.jfr.

As part of the instrumentation of commit(), when issuing invokevirtual instructions for this receiver, a proper downcast must be performed using checkcast.

Testing: jdk_jfr
