java.lang.OutOfMemoryError appears during build of android 2.1 on Mac OS X 10.6.8

This is a build issue I’m struggling to solve. I’m trying to build Android 1.5 on Mac OS X 10.6.8 with jdk 2.1. The “make” command ran for a while, and finally, it said:

The system is out of resources.
Consult the following stack trace for details.

It seems that the Java heap size is not enough. I googled this issue and it gave me several links such as:

• How to deal with “java.lang.OutOfMemoryError: Java heap space” error (64MB heap size)
• Change Java heap size on a Mac

These pages mainly suggest adding the “-Xmx” option to JVM Options. I tried the following:
Added this column in /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0-leopard/Resources/Info.plist

VMOptions
-Xms1024M -Xmx2048M

(I also tried setting up VMOptions.x86_64 instead of VMOptions).

After another link (osdir.com/ml/android-platform/2010-06/msg00097.html), I also changed the following line in the build/core/definitions.mk file in the android build directory.

$(hide) java -Xmx512M -jar $(HOST_OUT_JAVA_LIBRARIES)/proguard-4.0.1.jar \

to

$(hide) java -Xmx2048M -jar $(HOST_OUT_JAVA_LIBRARIES)/proguard-4.0.1.jar \

None of the above helped. I have a few questions :

• Whether it can be changed system-wide
  Java heap size on Mac OS X, is this the right way to go? If so, are the changes I made in the Info.plist file achievable?
• Or I have to change the heap size
  Built specifically for Android? If so, what should I do?

Edit

Just an update: I tried building android 3.1 with jdk 1.6 and the build went smoothly. (even if the “-Xmx” option is not set for JDK 1.6). I still don’t know what went wrong when building 2.1 with jdk 1.5.

Sometimes OutOfMemoryError is not due to insufficient Heap. Try adding PermGen:

-XX:PermSize=40m
-XX:MaxPermSize=240m

Sometimes it is also caused by the poor size of Young and Ternured. Still others should perform Full GC for a long time and have a low percentage of collection.
