Enable Remote Debugging on a Java Server

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5001

The best documentation on this is available from InformIT. This site details the following parameters:

-Xdebug : Enables the application to be debugged.
-Xnoagent : Disables the sun.tools.debug agent so that the JPDA debugger can properly attach its own agent.
-Djava.compiler=NONE : Disables the JIT (Just-In-Time) compiler.
-Xrunjdwp : Loads the reference implementation of the Java Debug Wire Protocol, which enables remote debugging.

	Notes on Collections

	By default, Scala uses immutable collections. However, there are mutable
	versions available (in the scala.collection.mutable package). The most common
	collections are List, Set, and Map.

	Playing with Scala Traits, a nice way to add (mixin) functionality
	to classes using the decorator pattern.

	With traits, the evaluation occurs left to right. Traits can be
	applied to class/trait definitions in addition to objects, as
	demonstrated by the class ContinuousIntegration
