AvoidCatchingNPE

Code should never throw NullPointerExceptions under normal circumstances. A catch block may hide the original error, causing other, more subtle problems later on.


            
//CatchStatement/FormalParameter/Type
 /ReferenceType/ClassOrInterfaceType[@Image='NullPointerException']
 

Example(s):


  
public class Foo {
  void bar() {
    try {
      // do something
      }  catch (NullPointerException npe) {
    }
  }
}
