SYNCH.NESTEDS
When a synchronized method calls other synchronized methods on same object, it does not create synchronization problems but it does have a detrimental effect on performance. This error is reported for static method calls.
Example 1
12 public static class MyClass {
13 static public synchronized List getElements() {
14 return internalGetElements();
15 }
16 static synchronized List internalGetElements() {
17 List list = new ArrayList();
18 // calculate and return list of elements
19 return list;
20 }
21 // ...
22 }
SYNCH.NESTEDS is reported for line 14: Synchronized static method calls another synchronized static method 'internalGetElements' with the same lock held
