It hangs in at jdk.internal.org.objectweb.asm.MethodWriter.visitMax
infinite loop when calculating max stack. A respective task for
investigating this particular issue has been created (JDK-8160673).
However, in order to have jittester tests generation more stable in
general for automatic tests generation, a patch for current
issue(JDK-8160276) is needed.

>> Jittester hangs in rare cases of specific seeds, so, fix launch test generation in separate thread and check for generation timeout. Test is generated again with next seed in case timeout was hit.
