Getting an error(MESSAGE A handler conflict occurred. This may disable some commands) when launching eclipse

问题

I developed one plugin(RMP) in eclipse 3.3.2 where i am creating menu items dynamically. I ran the application and it is working fine and am able to see the menu items created dynamically.

Now I exported this plugin(RMP). I added this in plugin folder of eclipse 3.4 installation. Now I launched eclipse and I am able to see all the functionalities implemented in my plugin(RMP) but the menu items created dynamically are invisible. When i click on menu, nothing is coming.
Pls find the error log below for more information. I took this log from my workspace -> .metadata folder.

Log:

Requesting help in this regard, Thanks in advance.

Try launching your eclipse3.4 with the -clean option.

If a -clean is not enough, the problem lies in the definition of com.ericsson.eadt.apstoolsintegrator.actions.APSToolAction.

If it is an action set, check its definition: a keybinding used might be in conflict with legacy eclipse3.4 keys definition.
