Answer 1

Java, by default, does not uses all avalaible memory. You need to run the application with the corresponding parameters.

See this question to all the details. (It can change with the version of Java).

The parameter setting can be set on the command line but if you use an application you may have some configuration file. For example, in Eclipse you have eclipse.ini where you an set your memory preferences.
