How to byepass a older version jar with new?

Question

I have written a class mediator and used it in wso2 esb which uses ehcache-core-2.6.6 jar so i have put this jar in \esb_home epository\components\lib folder but here is the twist, I have a jar as ehcache_1.5.0.wso2v3 jar in esb_home epository\components\plugins. This jar comes with wso2 esb. Now when i run my proxy containing the class mediator, it takes refrence of ehcache_1.5.0.wso2v3 jar instead of ehcache-core-2.6.6 jar so due to this i am getting error as:

[2013-05-14 17:10:59,898] ERROR - NativeWorkerPool Uncaught exception

        at java.lang.Thread.run(Thread.java:722)

So, my question is how can i byepass the jar ehcache_1.5.0.wso2v3 when running my proxy and refrence the jar ehcache-core-2.6.6 which i need to refrence?Looking forward to your answers. Thanks in advance

I have followed what ratha has mention in his reply to this question but after doing those steps, i am getting this error and my esb doesn't get started:
