Summary: ContextConfig - unnecessary null checks
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: s...@apache.org

Patch to remove null checks
Sample code:
urlPatterns = processAnnotationsStringArray(evp.getValue());
urlPatternsSet = urlPatterns != null && urlPatterns.length > 0;
for (String urlPattern : urlPatterns) {
The check "urlPatterns != null" is unnecessary as the method call never returns
null.
If it could return null, then the for loop would cause an NPE.
