Making changed to bytecodeInterpreter.cpp

[Kumar Saurav]

Hi,

I have installed icedtea6-1.11.4 and am trying to modify 
bytecodeInterpreter.cpp to trap branch conditions. Once I make changes 
to trap branch conditions and try to do "make hotspot" in the 
icedtea6-1.11.4 main directory, it works. But when I try using just 
"make" the build stops with the following error:

-def-build-bootstrap-tool:

build-bootstrap-javac:
mmap failed for CEN and END part of zip file
       [jar] error while reading original manifest in file: 
/home/icedtea6-1.11.4/openjdk.build/langtools/build/bootstrap/lib/javac.jarnull
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32756 bytes for 
ChunkPool::allocate
# An error report file with more information is saved as:
# /home/icedtea6-1.11.4/openjdk/langtools/make/hs_err_pid5811.log
make[3]: *** [build] Error 1
make[3]: Leaving directory `/home/icedtea6-1.11.4/openjdk/langtools/make'
make[2]: *** [langtools-build] Error 2
make[2]: Leaving directory `/home/icedtea6-1.11.4/openjdk'
make[1]: *** [build_product_image] Error 2
make[1]: Leaving directory `/home/icedtea6-1.11.4/openjdk'
make: *** [stamps/icedtea.stamp] Error 2

I read the log file and it mentioned that one of the things I should try 
is to reduce the Java heap size. So, I used the flag -Xmx256m in 
/acinclude.m4 but this didn't help.

Can you suggest the build process to follow if we make changes to files 
like bytecodeInterpreter.cpp and bytecodeInterpreter.h?
