we run sometimes into this error (especially on some virtualized windows machines) :

java.lang.RuntimeException: 'force inline by CompileCommand' missing from stdout/stderr
at jdk.test.lib.process.OutputAnalyzer.shouldContain(OutputAnalyzer.java:221)

Maybe we do not reach the "force inline" action so the output is missing.
