FULL PRODUCT VERSION :
java version " 1.7.0_11 "
Java(TM) SE Runtime Environment (build 1.7.0_11-b21)
Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
When using java.util.Scanner the method next is ignoring delimiter newline and method skip is not ignoring the delimiter.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached Unit test.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Both tests should pass.
ACTUAL -
Test 1 fails. And it is hard to find out why.

REPRODUCIBILITY :
This bug can be reproduced always.
