Unable to start guidewire PC server from tomcat

Question

We have been trying to start the policycenter server from tomcat. The server is getting started even though it throws exception with the message "PolicyCenter unable to start" in the logs. Please find the log details below.

Caused by: java.lang.SecurityException: class "org.osgi.service.log.LogLevel"'s signer information does not match signer information of other classes in the same package

I just deleted a couple of signatures from org.eclipse.osgi-3.13.300.jar and everything started up! I found it by searching, then I opened the META-INF folder with winrar and deleted ECLIPSE_.SF and ECLIPSE_.RSA
