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
