After I got caught doing an unnecessary check on the return value of
NEW_C_HEAP_ARRAY (a mistake that I copied) I thought it would be good to
do a cleanup in the sources so that others would not fall into this
trap. This is the result.
I have removed some places where the VM will be shut down after
NEW_C_HEAP_ARRAY returns NULL (it never does return NULL, it does
instead exit). I have also removed lots of unnecessary casts, that might
There are /numerous/ buggy usage that I have NOT fixed. Those are bugs
that ought to be fixed, but they are not in the gc folder, and I am
unsure about the best solution (the do not just directly exit the VM). I
have created a BUG to track them
(https://bugs.openjdk.java.net/browse/JDK-8230395), and I will leave
them for others to solve.
I have changed some code paths that I can not test (AIX for example) so
it would be nice if someone could verify it works there.
