Actually, I've just been discussing this with Red Hat's gcj people in
connection with a different project. What they say is that the Java
security manager is completely implemented now, but what is still
missing is that it's possible to bypass Java security if you can execute
untrusted bytecode. So if I understand correctly, a gcj environment is
secure as long as you can prevent hacked-up class files from getting
into your classpath.
