Description
The test runtime/NMT/HugeArenaTracking.java reintroduced with JDK-8234270 fails on Windows 32bit.
On Windows 32 bit the address space is only 2GB if the binaries do not have the LARGEADDRESSAWARE flag set. As the java binary is linked without this flag it cannot allocate more than 2GB.
The test tries to allocate 2GB+ in a loop - this will always fail on Windows 32bit.
I would suggest to problem list the test for Windows 32bit.
Comments
Fix request (8u): Fixes runtime/NMT/HugeArenaTracking.java to only run on 64-bit. Only modifies test, tested.

Fix request (13u) Requesting backport to 13u, the issue is present there too. The patch applies almost cleanly except for minor context difference in copyright comment.

jdk11 backport request I would like to have the patch in jdk11 as well, because the issue is present there too. The patch applies cleanly (except the copyright comment).

I thought Linux, by default, split the address space in to 3GB for user and 1GB for system? But simplest fix is to just restrict to 64-bit. Though I'll leave that for NMT folk to decide.

Just for the record: The test could run on Linux 32 bit. On Linux 32 bit executables can use up to 4GB adress space - not sure about other 32bit operating systems. But it might be best to only let it run on 64bit.

The test should be modified to only run on 64-bit using @requires.
