I was using Sun JDK 1.5.0 indeed. There is some info about memory
limits in Sun VM at [1]:

 maximum heap size:

    Smaller of 1/4th of the physical memory or 1GB. Before J2SE 5.0,
the default maximum heap size was 64MB. You can override this default
using the -Xmx command-line option.

However, it is only valid if the parallel gabage collector is used.
