Bug #: 52042
Summary: Possible NullPointerException in
DefaultInstanceManager#processAnnotations
Product: Tomcat 7
Version: 7.0.22
Platform: PC
Status: NEW
Severity: critical
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
NullPointerException exception is thrown randomly from
"DefaultInstanceManager#processAnnotations" method on the following lines,
List<AnnotationCacheEntry> annotations;
synchronized (annotationCache) {
annotations = annotationCache.get(clazz).get();
}
//Null Pointer Exception is thrown, because annotations is NULL
for (AnnotationCacheEntry entry : annotations) {
For example, I have a JSF Managed Bean
public class X extends Y{
}
Open JSF page that contains managed bean X. Randomly opening the same page
throws NullPointerException because for superclass Y "annotations =
annotationCache.get(clazz).get();" returns null.
Using WeakHashMap on "annotationCache" field may be the reason of exception.
