serviceability/sa/ClhsdbDumpclass.java test fails on all debug builds producing invalid classes.
https://bugs.openjdk.org/browse/JDK-8294969 "Convert jdk.jdeps javap to use the Classfile API" introduces more strict class checking.
serviceability/sa/ClhsdbDumpclass.java test log newly contains numerous errors where field instructions point to method type descriptors. The test fails when an error occurs in the log.
Affected are only debug builds of the JDK on all systems.

Sample of the errors from the log:
