Sounds like you have added Jars to the old environment that are not in the new environment.
What is the offending code that causes the error? What were your customizations against the 6.0.35 environment? Is the Woodstox StAX jar in the web application or Tomcat lib directory? Where was it previously? Did you test this before you migrated causing this “urgent” issue? What is different between your test and this urgent outage’s configuration. -Jason From: Lavitesh Verma [mailto:lavitesh.ve...@amdocs.com] Sent: Monday, June 15, 2020 8:16 AM To: email@example.com Cc: RUBIN, JACOB <jr2...@att.com>; lsrv...@list.att.com; Vasudev Wadhawan <vasudev.wadha...@amdocs.com> Subject: [tomcat-users] Issue found during migration of Tomcat version 6.0.35 to 8.5.5 Importance: High Hi Team, Below are the details of the system and tomcat version Old tomcat version: Apache Tomcat/6.0.35 New tomcat version: Apache Tomcat/8.5.5 Operating System: SunOS OS Version: 5.10 Architecture: sparcv9 JVM Version: 1.8.0_101-b13 Vendor: Oracle Corporation We are trying to migrate Apache Tomcat version 6.0.35 to 8.5.5.
