Scary file... Is that the original version? If it's the original, please
apply. If not, please apply the original and then adjust it. This makes
tracking merges easier.
Two small things before you commit:
- Put the file in include/j3/openjdk/jvm.h, as this will be very specific to
OpenJDK
- Add the file in the third party software list of LICENSE.txt file, like
this: just after JNI write:
OpenJDK vmkit/include/openjdk/
Thanks!
