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.
