Kathey Marsden resolved DERBY-5500.
-----------------------------------
Resolution: Invalid
The resolution to this issue in the JVM was to change the default maximum heap
from 1/2 the physical memory up to 2GB to 1/2 the physical memory up to just
512MB. The changes are impleented and documented in IBM java 7 SR1 and affect
both Windows 32 bit where the out of native memory problem was an issue and 64
bit where the problem did not exist. This aligns Windows with other platforms
but means that applications formally relying on a default max heap larger than
512MB might have to set it explicitly with -Xmx
