Hello,
The variable ARCH_DATA_MODEL is not initialized anywhere. I know JPRT
sets it, but I don't think we should rely on that.
./autoconf/buildjdk-spec.gmk.in:ARCH_DATA_MODEL := $(OPENJDK_BUILD_CPU_BITS)

Tim,
The problem only appears on 32-bit Windows, but the fix appears to be
across the board.
Does this penalize or otherwise adversely affect test runs on other
platforms?
Good point. Here is an updated webrev where serialGC is requested
only on 32 bit platforms:
http://cr.openjdk.java.net/~tbell/8166648/webrev.01/
This change tested OK in JPRT on the following platforms:
solaris_sparcv9_5.11-product-c2-langtools_jtreg
solaris_x64_5.11-product-c2-langtools_jtreg
linux_i586_3.8-product-c2-langtools_jtreg
linux_x64_3.8-product-c2-langtools_jtreg
macosx_x64_10.9-product-c2-langtools_jtreg
windows_i586_6.3-product-c2-langtools_jtreg
windows_x64_6.3-product-c2-langtools_jtreg
I inspected the test logs to verify -XX:+UseSerialGC is passed only
during 32-bit testing.

Hello
The change of HotSpot runtimes on 32-bit Windows [1] has been a source
of langtools test failures due to memory space exhaustion.
On our Windows build/test clients, the combination of the C2
runtime and
parallel GC causes about 20 extra threads to be started in each VM.
These added thread stacks, plus heap management in C2, result in too
much memory pressure to fit the workload into 32-bit VMs.
This fix will run langtools jtreg tests using the serial garbage
collector instead of using the default collector (parallel GC).

Testing:
-5 out of 5 jobs (with the fix) passed langtools testing
-4 out of 5 control jobs (without the fix) failed testing in
windows_i586_6.3-product-c2-langtools_jtreg
Thanks in advance-
