12  * An extension of the JGroups MethodCall class. The reason for this subclass is a minor
13  * optimisation in the way method IDs are dealt with. The JGroups class of the same name uses
14  * a short as a method id, which is more efficient as far as network streaming is concerned.
15  * <p/>
16  * However, JBossCache uses this id for a lot of == and switch comparisons. Java, being an
17  * integer oriented virtual machine, goes through a lot of extra steps when performing such simple
18  * comparisons or arithmetic on non-integer numeric types.
