_____________________________________________________
Change the compiler level to 1.5() recompile and deploy to server.

Below are a list of some of the version numbers and their corresponding Java runtimes:
Version 50.0 = Java 1.6.x
Version 49.0 = Java 1.5.x
So there is mismatch of Java versions..
