Since you don't mention it in your note, I assume you are not
aware of the '-Xmx<size>mb' option to the JVM. This allows you to set
the max size of the Java Heap (I think it defaults to 64MB). For such
a large file you might save time also specifying '-Xms<size>mb' which
is the starting size of the heap (reduces the number of Full GC's).
So I suggest something like:
java -Xmx500mb -Xms100mb -jar batik-squiggle.jar
You might be able to set these through the Java control panel on
Windows, but I usually do this stuff from the DOS prompt.
