There might be other occurrences of B_FILE_NAME_LENGTH in the source
code. I believe there's also a JVM_PATHLEN define in jvm_haiku.h - but
that one's already using the correct definition.

Java is generally quite liberal in allocating large chunks of memory
to use for its heap, even if it doesn't use it right away. There are
various options you can pass to the JVM to limit the heap size for
these steps. You might want to try tweaking various options e.g.
-Xms256m -Xmx512m which would give you an initial heap of 256MB and a
maximum of 512MB.
