the test will be quarantined by JDK-8067475 -> P4

Unhandled nightly bug -> P1
15-12-2014

Assigning to expert: Vladimir Ivanov.
17-10-2014

I did binary search on the changesets between b30 and b31 and it turned out that the timeout first occurs with changeset 10617 [1] which belongs to JDK-8050057. Still have to figure out what exactly causes the bug and why it does not occur without "-esa". Profiling with JFR did not show any suspicious traces. [1] http://hg.openjdk.java.net/jdk9/dev/jdk/rev/5793f9c37702

Doh.
07-10-2014

I did some more performance measurements and noticed that the regression only occurs with the "-esa" VM option to enable system assertions. Without this option b31 is as fast as b30 (or even faster). I suspect that JSR292 related changes added more assertions to code that is extensively executed by these tests.
07-10-2014

It looks like as if the timeout is caused by a regression introduced in b31: Running with b30: 1m 37s Running with b31: > 13m 57s
