Running gjdoc over all of GNU Classpath at once is pretty memory
intensive. I don't have a setup at this moment using jamvm. But a
natively compiled (with gcj) gjdoc seems to have a top virtual memory
usage of just above 300MB. So 1GB seems a bit much. But try generating
documentation first of just one or two subpackages to see if that works.
