Making changed to bytecodeInterpreter.cpp

[Krystal Mok]

Hi Kumar,

Could you post the crash log (/home/icedtea6-1.11.4/openjdk/
langtools/make/hs_err_pid5811.log) somewhere to let people get more details?

>From the log in your mail it doesn't look like a JIT compiler issue. This
list (hotspot-compiler-dev) is for discussion on HotSpot VM's JIT
compilers. The problem you're hitting looks more like a zlib problem, or
you might be really running low on memory.
It'll take more information on the problem to be able to redirect you to a
more appropriate list.

BTW, when you run "make" in the main directory, it'll build the whole JDK,
where as running "make hotspot" will only build the VM. If the latter is
sufficient for you to carry on your experiment, you might just want to
build the VM alone and save the trouble of dealing with this crash.
