Hi,

I am working on upgrading eclipse application from 3.2 to eclipse 4.1.1
buildId=M20110912-1510
java.version=1.6.0_12
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US

When I will try to launch the eclipse it throws following exception

!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.NullPointerException: The handler service cannot be null

org.eclipse.ui.internal.commands.WorkbenchCommandSupport.<init>(WorkbenchCommandSupport.java:75)

I had tried many configuration settings but still no luck. Can anyone know the cause of this exception?
Please let me know if there is any guide available to upgrade from 3.2 to 4.1.1

Thanks
