BUILD_JOBJC woes on Mac

[Alan Bateman]

I've have an up-to-date clone of jdk8/tl + a patch to code in the jdk 
repository that makes use of APIs that are new in jdk8. It builds/run 
happily on all platforms except Mac where it needs to build JObjC.jar.

Attached is the tail of "make LOG=trace" where it looks like JObjC.jar 
involves compiling jdk8 classes with -source/target 1.5. In this case 
the boot JDK is an update to date build of jdk7u-dev.

Does anyone have any insight in how JObjC.jar should be built? I 
remember Dan Xu ran into something similar recently with @Native and I 
suspect this is the same underlying issue (in Dan's case then the code 
didn't need @Native).

Thanks,

-Alan
