Ah yes indeed - good clue!
If so, another

I think my JDK_TOPDIR workaround is another clue,
that should be added to the bug report.
Since it appears that this bug is also in openjdk7,
I would make it a P2, just because of the extreme frustration
developers are likely to encounter.
The Makefiles could simply make JDK_TOPDIR absolute,
but that has the problem that FullPath is defined in a Makefile
included using a path that uses JDK_TOPDIR.
