Bug ID: 59255
Summary: 404 due to NullPointer in Mapper.java
Product: Tomcat 8
Version: 8.0.29
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: Catalina
Assignee: [email protected]
Reporter: [email protected]
Since update to Tomcat 8.0.29 we noticed problems in our Struts based
application. Some actions in random moments returned 404 errors without any
log. The same problem appeared in 8.0.30-33. We analyzed changes made between
versions 8.0.28 and 8.0.29 and by adding them one by one we found that the
problem is caused by org.apache.catalina.mapper.Mapper and new properties in
Context: mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled.
mappingData.context.getMapper...RedirectEnabled() throws in some situations
null pointer exception because mappingData.context in null.
After changing code of Mapper.java in Tomcat 8.0.33 and recompiling we
confirmed that
