Note, the recent failures in this bug describe only the problem with 17 resulting from the compilation policy work (JDK-8251462). The previously reported failures in the older releases are different and should be addressed separately if they still exist.

The problem with this is that the test expects that with (-Xcomp and -XX:-TieredCompilation) a method shouldn't be considered to be mature if it hasn't been invoked before. The way -Xcomp works with the tiered policy is by setting Tier4InvocationThreshold to 0, which in turn makes all methods mature, since CompilationPolicy::is_mature() uses a scaled version of the same predicates as the compilation switching logic.

[~kvn] - These two tests have started failing with 4 failures per Tier6 job set after the following bug fix was integrated: JDK-8251462 Simplify compilation policy The tests should be ProblemListed in the Xcomp config: compiler/jvmci/compilerToVM/IsMatureVsReprofileTest.java compiler/jvmci/compilerToVM/IsMatureTest.java

ILW = Test fails because method invoked multiple times is not detected as "mature" by JVMCI, very intermittent with single jvmci test, no workaround = MLH = P4 Marking this as test bug for now.
