Bug #: 52587
Summary: NPE in authenticator when no realm/resource is defined
Product: Tomcat 7
Version: 7.0.25
Platform: PC
OS/Version: Mac OS X 10.4
Status: NEW
Severity: minor
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: ch...@christopherschultz.net
Classification: Unclassified
When no Realm is available to authenticate against, an NPE is thrown.
STR:
1. Start with a stock 7.0.25 and modify server.xml:
2. Comment-out <Resource> in <GlobalNamingResources>
3. Comment-out <Realm> in <Engine>
4. Deploy manager app and try to log in
java.lang.NullPointerException
org.apache.catalina.realm.RealmBase.authenticate(RealmBase.java:340)
org.apache.catalina.authenticator.BasicAuthenticator.authenticate(BasicAuthenticator.java:158)

Clearly, this is a pathological setup, but it might be nice to get a decent
error message instead of an NPE.
