I use ant with -Xmx512M option and it reports an OutOfMemory exception java version "1.4.2_04" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05) Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode) --Tim
FWIW, I run with -Xmx128m (Linux, JDK 1.4.2_04) for doing clean builds from the command line and never have any such problems. What specifically are you doing? Steps to reproduce?
I have downloaded .tar.bz2 from netbeans.org and started "ant" from the shell
Dev sources w/ Ant 1.6.1?
cannot reproduce anymore. ant 1.6 with -Xmx128M works now
