Java puts code (as opposed to data) in PermGen space (i.e. space that
doesn't get garbage collected). The size of this space is fixed by default
but can be overridden with a command line argument. Maxima (along with the
Java code) probably contains too much code for the default java
configuration. You can increase this java default as follows:
java -XX:MaxPermSize=200M -jar /path/to/abcl.jar
This makes the max permgen space 200 MB. You may have to vary that number.
