The test had failed previously due to a message string copy in an old 2015 version of Assert class [1]. Please note getMessage is called not depending of lhs.equals(rhs) Modern code does not have that copying and I was unable to cause OOME in that spot, or in an area close to that spot, or in the test execution in general. The test will be un-quarantined. ======== [1] http://hg.openjdk.java.net/jdk/jdk/file/874d76e4699d/hotspot/test/testlibrary/com/oracle/java/testlibrary/Asserts.java#l166

This test is quarantined. ILW: I = L (testbug) L = M (intermittent) W = L (increase heap size) ILW=LML= P5

ILW=Test fail due to undesirable OOM, rare, none=MLH=P4 + nightly = P1
