Hi,

Please review: http://cr.openjdk.java.net/~jfranck/8009382/hotspot/webrev.01/ Bug is here: http://bugs.sun.com/bugdatabase/viewbug.do?bugid=8009382 In short, this is needed in order to implement the desired semantics for reflecting over type annotations after a class redefine. This is also needed in order to reduce the size overhead introduces on the JDK side in the current type annotations reflection implementation. A prototype of the jdk changes can be found here: http://cr.openjdk.java.net/~jfranck/8009382/jdk/webrev.00/

Can we not called them foo0? That trailing 0 doesn't give any value.

While in the neighborhood I also fixed a handful of unlikely but possible null dereferences and removed an unused resource mark. I have run jdklang on a fastdebug build to verify the removal of the resource mark in addition to manual verification (also Dan helped me look into this, but errors are mine). For Oracle reviewers, ccc is approved. testing done: jdklang with and without my prototype jdk changes x product/fastdebug vm.quick.testlist jprt standard build and test cheers /Joel
