Re: OutOfMemory errors

Soot is a research compiler, designed to make it easy to test new
analyses, rather than to run in a minimal amount of memory.

You will need to increase your heap size (using -Xmx 128m, for example)
to run soot on a whole application.

An alternative, if you are not doing interprocedural optimizations,
is to run soot on one class at a time, rather than all at once with
the --app option.
