This error has been seen once so far, on a JDK8 test run on Solaris SparcV9.

The test was run here: https://ci.adoptium.net/job/Test_openjdk8_hs_extended.openjdk_sparcv9_solaris_testList_1/81/consoleFull

Also, this issue may be related to https://bugs.openjdk.org/browse/JDK-8292686 because that is also a SIGSEGV seen while in a JFR frame, and TestGetEventTypes.java is mentioned in the final comment.
