do you have a good test case for us, cause this shouldn't happen
public Enumeration findResources(String name) throws IOException {
if (log.isDebugEnabled())
log.debug(" findResources(" + name + ")");
Vector result = new Vector();
int jarFilesLength = jarFiles.length; -->this is line 946
the variable jarFiles is instantiated to (new JarFile[0]) when the
webappclassloader is created.
When it is stopped, jarFiles=null, becomes null.
So your app is trying to load a class from the webapp after the webapp
class loader has been stopped.
Even if jarFiles got reset back to (new JarFiles[0]) upon stop(), you
would get a ClassNotFoundException as there is nothing to load from.
I'd be interested to see if this was reproducable, if so, open a defect
and attach the test case.

Hi all,
Some strange thing. I am using axis SOAP jars. When I start Tomcat my
SOAP messages are ok..when I restart the webapps via the Tomcat
Manager I get a null pointer exception, see below. After restart
Tomcat it works ok. So seems wrong with classloading but why only when
I restart via the tomcat manager?
Someone any idea??
