So this is a new bug that needs filing?  I think it's sort of a duplicate, see below.

Solaris 10 10/09 s10x_u8wos_08a X86
Builds with jdk8, fails with jdk7.

I am pretty sure that the cause of the bug is a dependence (in WrapperGenerator) on the order in which items are iterated out of a hash table.  That appears to have changed in the transition from jdk7 to jdk8.  That change was apparently necessary to make it (very much) harder to DOS a hashtable with collisions.  I observed different output running WrapperGenerator with the exact same inputs under 7 and 8, cutting and pasting from a build and replacing only the target directory and the host VM.

It seems to be fixed in jdk8-build as of six days ago (I checked), as a side-effect of fixing 8004151
