Exception: net.sf.saxon.Configuration signer information does not match signer information

Hi Team,

We are getting below exception:

java.lang.SecurityException: class “net.sf.saxon.Configuration$ApiProvider”'s signer information does not match signer information of other classes in the same package at java.lang.ClassLoader.checkCerts(ClassLoader.java:891)

This error is occuring for all SOAP integrations, ootb Activity InvokeAxis2 in Rule-Connect-SOAP from Pega-IntegrationEngine:07-10-27 fails in java step 5.

Any leads would be highly appreciated.

Warm regards,

Suhas
