Deutsche Bank(Australia) sees a crash in C2Compiler, 6.0u7.
Workaround would be exclude method and implemented.

The stack trace looks similar to 6687945 but there is no other info to confirm the same.

And maybe pure coincidence, there is another compilation underway.

The files are at /net/cores.central/cores/70389736/suncase_70389736 if you want a quick look.

The relationship b/w OMFIXTranslator.translateToOMAmendOrder and translateAmendQuantities, translateToOMAmendOrder invokes translateAmendQuantities, thats all.

Cu is reluctant to test with 6.0u11.

And getting OMFIXTranslator.translateToOMAmendOrder to fail in
compilation in their test environment proves to be quite difficult.
