I have a certain application running using the JNI (more specifically, RPG
calling Java Excel POI HSSF) to create a really large spreadsheet, and its
running out of memory/heap. We're running a 64bit JVM. If I can figure
out how to specify a larger maximum heap size, can I go beyond the current
2GB limit? Is there a way to alter the maximum heap size for a job? If
not by job, by default?
