Building JDK8 fails on OS X El Capitan: clang process gets stuck

[Robin Stevens]

Hello,

if you follow the build instructions to the letter (
http://hg.openjdk.java.net/jdk8u/jdk8u-dev/file/817d9fb584ba/README-builds.html),
and try building JDK with XCode version 4.5.2 on El Capitan, the build
never ends.

At a certain point, you have a number of "clang" processes each consuming
one CPU core for 100% which never end.

Using XCode version 4.6.3 solves the issue.

Can this be added to the build instructions ? It would have saved me a
considerable amount of time if this would have been mentioned in the
documentation.

Thanks,

Robin
