java.util.zip.ZipFile.getEntry
Product: Tomcat 8

OS: Linux
Status: NEW
Severity: normal

Hi,
I'm running an application developed in a rather outdated version of Grails
(2.2.4).
The application still works fine with Tomcat 8.5.49, but breaks with 8.5.50.
On startup, I get the following in catalina.out:

I have checked the code in ZipFile.java: getEntry - and it has:
public ZipEntry getEntry(String name) {
if (name == null) {
throw new NullPointerException("name");
}
So I assume something in the classloader chain started passing null as the name
to JarFile.getEntry (which delegates to ZipFile.getEntry).
In the org.codehaus.groovy.grails.web.context.GrailsContextLoader, I could see
the initialization starts with
application = ctx.getBean(GrailsApplication.APPLICATION_ID,
GrailsApplication.class);
... and than bails out with the messages I see (but the actual exception
appears to happen in a worker thread)
I so far haven't been able to trace what happens in-between.
And I don't know if this is related to #63970 and/or other changes to
CachedResource.java done recently... but linking it here in case it's relevant.
Any help on this would be much appreciated - thanks a lot in advance.
Cheers,
Vlad
