What version of Java™ should I use?

What do I do if I get a Java™ out-of-memory error?

HANDLE.NET FAQs
If you get an out-of-memory error (or would like to increase the amount of memory that the server can use), add the "-mx128m" argument when running java/jre. In fact, we recommend increasing the amount of memory available to Java to allow Java and the server to use up to 128 megabytes of virtual memory, if necessary. Alternatively, the config.dct file can be edited to cut down on the amount of memory used by changing the number of threads allocated for each listener.
