openjdk,icedtea - Xmx option mandatory

Fri Aug 8 16:33:53 PDT 2008

In the while, I downloaded from:
https://api.opensuse.org/build/openSUSE:Factory/standard/i586/java-1_6_0-openjdk/java-1_6_0-openjdk-1.2_b09-18.16.src.rpm
the last factory opensuse java version.

If I'm not wrong, the Xmx setting is done into the file:
openjdk-6-src-b09-11_apr_2008-fedora/openjdk/jdk/make/docs/Makefile

Where the default size should be:
MAX_VM_MEMORY = 512

That default value makes the process crash on my PC, which has 512 mb
of RAM (java -Xmx512m -version crashes, too).

I think the SUN default value was 384 - see:
https://jdk-jrl-sources.dev.java.net/source/browse/jdk-jrl-sources/jdk6u3/trunk/j2se/make/docs/Makefile?view=markup

In my PC, I can run successfully:
java -Xmx384m -version

If this discussion of default value was correct would mean that
default openjdk / icedtea RPM
versions will not work out of the box (without patches) on PCs with
scarce RAM like mine. What do you think?
Ciao
