After updating to ASM6 two nashorn tests fail test report attached.
test/script/basic/compile-octane-normal.js and
test test/script/basic/compile-octane-normal.js

The failures can be reproduced by applying the following patches
asm6.patch and asm-update.patch to the jdk repository.
The first are the changes from the ASM repo the second are
the changes to the jdk repository to get a full build.

It is not clear at this time, if this is a bug with ASM or with nashorn.
