[~ccheung]Thanks for additional logs. As the test explicitly specify -Xmx4M in @run main/othervm, it overrides the heap size settings passed in. In the solaris/sparc log from Calvin, it shows 4M is committed for the java heap. The fix is to use larger java heap for the test when the CDS mode becomes default.
