Bug ID: 65273 Summary: NoClassDefFoundError in Apache POI dependency after upgrading to Tomcat 8.57 in Jira Product: Tomcat 8 Version: 8.5.57 Hardware: PC Status: NEW Severity: major Priority: P2 Component: Packaging Assignee: dev@tomcat.apache.org Reporter: angelica.sala...@easesolutions.com Target Milestone: ---- Hello, I am unsure if this is the correct channel to make this report. Let me know either way. I am from Easesolutions, vendor of R4J - Requirements Management for Jira. In our application, we are using the Apache POI library to support our Word Export capabilities. Recently, we have been receiving reports from customers with the same error: java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.openxml4j.opc.internal.marshallers.ZipPackagePropertiesMarshaller java.lang.NoClassDefFoundError: Could not initialize class org.apache.poi.openxml4j.opc.internal.marshallers.ZipPackagePropertiesMarshaller at org.apache.poi.openxml4j.opc.OPCPackage.init(OPCPackage.java:161) [?:?] at org.apache.poi.openxml4j.opc.OPCPackage.<init>(OPCPackage.java:141) [?:?] at org.apache.poi.openxml4j.opc.ZipPackage.<init>(ZipPackage.java:97) [?:?] at org.apache.poi.openxml4j.opc.OPCPackage.open(OPCPackage.java:324) [?:?] This looks like a dependency/classpath issue. The thing is, we have not changed our POI dependencies since 2017 and have released several versions with no change and now it's suddenly acting up. And after trying many things, we are now very lost. Ref to our developer community post: https://community.developer.atlassian.com/t/class-cannot-be-loaded-when-restarting-jira-software/47421/3 This is being experienced intermittently by customers. For example, some have our application with the same version installed in multiple nodes but only experience the issue in 1 node. We have not been able to reproduce the issue in our own environments. It seems that the common action for all these customers before experiencing the issue was that they upgraded Jira to a version that had Apache version 8.57 and up. Ref: https://confluence.atlassian.com/jiracore/bundled-tomcat-and-java-versions-1013854250.html Hope you can help point us in the right direction.
