Hi Peter/David, catching up after long weekend. Why would there be an
OOME in object heap due to class loading in perm gen space ?
The perm gen is not a problem her (JDK 8 does not have it and we see
OOME on JDK8 too). Each time a class is loaded, new java.lang.Class
object is allocated on heap.
For the bootloader classes I thought, but could easily be wrong, that
the Class mirror did indeed go into the PermGen. But still this is not
relevant on JDK8 where there is no PermGen. It maybe that changed as
part of the early PermGen removal prep work that did go into 7u.

I'm on linux, 64bit and using official EA build 121 of JDK 8...
But if I try with JDK 7u45, I don't see it.
So what changed between JDK 7 and JDK 8?
I suspect the following: 8007572: Replace existing jdk timezone data
at <java.home>/lib/zi with JSR310's tzdb
