bug: JAR file entry hash table uses too much memory (zip_util.c)
This submission is just a one-liner fix that changes 64-bit structure
member alignment. The savings are only half as noted in the original
bug description, but still significant:
HelloWorld: about 150KB.
Eclipse: about 540KB.
This benefits all 64-bit VMs, as well as 32-bit VMs that are built with
ABIs that require 8-byte structure alignment for jlong (e.g., as ARM EABI).
(I have another fix that would reduce memory usage further, but it's
too risky now and I may wait till JDK9).
I usedhttp://hg.openjdk.java.net/hsx/hotspot-rt/. Not sure if this is the
right repo to use.
+ JPRT -- To verify build-ability; JPRT also runs jtreg jdk/tools tests
on all platforms. This includes basic JAR file tests.
+ Manually ran UTE/vm.quick.testlist on Linux/x64
