A DESCRIPTION OF THE PROBLEM :
Filter a XMLStreamReader using a StreamFilter that accepts certain elements. Then the first accepted element won't be reported as a START_ELEMENT event.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See the provided test case.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The first accepted element should be reported as a XMLEvent.START_ELEMENT.
ACTUAL -
The first accepted element is not reported as a XMLEvent.START_ELEMENT.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No direct error message.

REPRODUCIBILITY :
This bug can be reproduced always.
