java.lang.OutOfMemoryError: Java heap space while bootstrapping OpenJDK

[Ismail Dönmez]

Hi all,

I cloned latest OpenJDK off HG forest tree. And I am using jdk 1.6 to 
bootstrap, to be exact :

[~/jdk7]> javac -version
javac 1.6.0_03

All sanity tests passes but when I try make, I get :

===========================================================================

# Running javac:
/opt/sun-jdk/bin/javac -sourcepath ../../../build/linux-i586/gensrc:../../../src/solaris/classes:../../../src/share/classes -d ../../../build/linux-i586/classes 
@../../../build/linux-i586/tmp/sun/java.awt/.classes.list


The system is out of resources.

The machine have 1 GB RAM but I tested on a machine with same JDK but 2 GB of 
RAM but the same problem happens. Do I need more RAM or something else is 
going on here?
