IV20345: AN ABSTRACT CLASS DOES NOT INHERIT ALL ABSTRACT METHODS FROM ITS DIRECT SUPERINTERFACES.

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  On running Class.getMethods(), the returned array (containing
  public member methods of the class) has only one copy of the
  method, which had same signature and was present in multiple
  interfaces. The array of methods returned by Class.getMethods()
  contained following methods:
  1.wait
  2.wait
  3.wait
  4.equals
  5.toString
  6.hashCode
  7.getClass
  8.notify
  9.notifyAll
  10.method_M   << Only one copy of the method which was present
  in multiple interfaces.
  

Local fix

Problem summary

• If there are two interfaces, both having a method with same
  signature (for example: m(java.lang.String)) and there is
  another abstract class, which implements the two interfaces,
  then, on using "getMethods()" for retrieving all public member
  methods of the abstract class, only one copy of method "m" is
  returned.
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR14
  6.0.0 SR11
  6.0.1 SR2
  7.0.0 SR1
  .
  The JVM has been updated and a class now inherits all the
  abstract methods from its direct superinterfaces.
  

Temporary fix
