While accessing the hmc following exception is thrown:
HTTP Status 500 - Error while processing internal filterchain. Exception occurred at chain position: 4 of 8. Current filter: 'de.hybris.platform.servicelayer.web.SessionFilter@7caa05f8'!; nested exception is java.lang.NullPointerException
This does not happen every time but sometimes it is very frequent.
It has started coming after we migrated from 5.2. to 5.5
