Any idea what's causing this issue?

Can you double check your JDK Version? Do you have multiple versions of JRE libraries in your classpath?

Hi Sri,

Thanks for your reply. The issue got already resolved.
My os is windows 7 64 bit. I was using eclipse 32 bit and jdk 32 bit.
I just switched to 64 bit version of eclipse and jdk and everything
was all set.
