Cause

There is a compatibility issues with the user-installed plugin and the version of JIRA after the upgrade. In this case, the below suggest that it is a class from Innovalog's JIRA Misc Workflow Extension plugin that is having the compatibility issue.

com.innovalog.jmwe.plugins.functions.AssignToRoleMemberFunction.execute(AssignToRoleMemberFunction.java:95)

Resolution

• Update the third-party plugin to the version that is compatible with JIRA version. You can refer to http://marketplace.atlassian.com for more information.

• If there is no compatible version, please disable/remove the problematic plugin from JIRA and contact the developer of the third-party plugin to update the plugin compatibility.

  This steps could apply for other third-party plugins as well.
