Bug #: 51586
Summary: ContextConfig.checkHandlesTypes() doesn't check for
VerifyError when loading class
Product: Tomcat 7
Version: 7.0.19
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: you...@gmail.com
Classification: Unclassified
I've recently upgraded to Tomcat 7 and used to run with
metadata-complete="true" in my web.xml. With Servlet 3 I decided I'd try some
of the annotation features. When I turned off metadata-complete I got a
VerifyError trying to load one of my classes. This class is meant to only work
on Tomcat 6 so the fact Tomcat 7 cannot load this class is expected. What is
not expected is that Tomcat 7 doesn't just ignore the error and continue
scanning for annotations. Looking in ContextConfig.checkHandlesTypes() I
checks for virtually every type of loading failure except VerifyError. Perhaps
VerifyError should be added to this list?
