migration toolkit: failed at java loader if -Xmx value is too high
I'm attempting to migrate a 600meg HSQLDB to MySQL, and I have a process sorted that works with small HSQLDBs just fine. However, for large ones the migration toolkit runs out of memory. Without adjust -Xmx values, it fails after reading in about 300megs of the HSQLDB. I can set -Xmx512m and it will fail at about 500megs.
The problem I have is that if I set -Xmx to anything over 580m, the migration toolkit will fail at initializing java loader.
This is on Windows XP 32bit, 3GB ram (2.5GB un-used), and jre 1.6 update 17 (no other java versions installed. I have tested with jre 1.5 update 22 with the same results).
Any ideas?
