This cleanup looks good. To answer my own question (which you wrote earlier), it looks like jmap uses this code and I assume the work on SA.NEXT will address the duplication.

Thanks, Coleen

Hi,

Please review this change to fix: https://bugs.openjdk.java.net/browse/JDK-8033440 Webrev: http://cr.openjdk.java.net/~sjohanss/8033440/webrev.00/ Summary: The compactibleFreeListSpace has been updated to use an AdaptiveFreeList instead of a FreeList. This change has not been done for the SA and it leads to using a too small element size when walking through the list. When fixing this I realized that FreeList and some other type declarations associated with it weren't used by the SA, so I went ahead and removed them. I (or Eclipse) also changed the Java *-imports to be specific ones. Testing: * JPRT for build and sanity. * UTE run for tests listed in bug. * Aurora run for tmtools.testlist. Thanks, Stefan
