Hello,
several days ago I’ve proposed some improvements into asm library:
- https://gitlab.ow2.org/asm/asm/commit/ef945457bc19dbc09c02bd21b52f1950990f33f7
- https://gitlab.ow2.org/asm/asm/commit/9b914d524b7fe7ea694fc11ec784e67133ba383f
The patches were accepted and then it turned out the code I’ve patched is
similar to what we have in JDK.
So I propose the same changes to be accepted into JDK 12. They improve code by
using more simple constructions and replacing redundant hand-written code with
JDK-provided API.
I assume the JDK will get your performance fix at the next ASM refresh.
We've tried to avoid changes to ASM where possible as it complicates
upgrading. There are of course times when the JDK's copy of ASM is
modified to support changes to the class file before they are finalized
and in a ASM release but we usually don't apply other patches unless
they are really needed.
