Fatal error when starting Tomcat mongrel plugin from inside eclipse

I am trying to start Tomcat from within eclipse using the Mongrel plugin. Mongrel plugin adds start/stop/restart buttons on the eclipse main window. When I click on the start button I get this error.

I have multiple jdks / jres on the machine. Is this causing the error ? I think I have configured my environment variables correctly. JAVA_HOME, PATH etc.

Error I am getting on the eclipse console window:

Got this resolved. Putting the answer out here and hope this might help someone.

Basically I had multiple JRE's on my machine and due to a misconfiguration on my side, Tomcat was trying to use files from 2 different JRE's.

To fix it, I went into eclipse Preferences -> Mongrel -> JVM settings. Under the Boot classpath, I put the rt.jar from the jre which tomcat was using to launch.
