The patch is okay, I just pointing out that disabling CDS will sometime 
help on Windows 32-bit, assuming it is enabled by default.

The "testbug" label is used to tag test only issues, encoding in the bug 
description/commit message isn't really reliable. Yes, some areas have 
used "[TESTBUG]", there was a time when some people put a "TEST-BUG" 
prefix. There isn't a JDK-wide convention (at least not to my knowledge).
