The JDK files I got via the DYLD_LIBRARY_PATH are in a download from this file:
  http://download.java.net/jdk7u4/archive/b12/binaries/jdk-7u4-ea-bin-b12-macosx-amd64-16_feb_2012.dmg

I got it from here:
  http://jdk7.java.net/macportpreview/

--------
	/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/bin/java -fullversion
java full version "1.7.0_04-ea-b12"

This is also the ALT_BOOTDIR I use for builds.

When I built my own copy of hotspot (including gamma) I used a jdk8 repo (hsx/hotspot-comp/{hotspot,jdk,langtools}), plus your patches for 7113349.

I wouldn't be surprised if there were random problems running a JDK8 gamma on top of a libjava.dylib from 1.7.0_04.

No, I don't set that, but the example commands I sent have settings for it.

What's confusing (but maybe unimportant) is that the bug Stuart and I saw manifests only when libjava is put on the DLLP, but it does not manifest when the same libjava is loaded by some other unknown means.  (The loading can be traced with DYLD_PRINT_LIBRARIES, as shown in my message.)
