Problem:
   The test used shell script that diffs output got form the test. If 
there are warning, test fails.

Fix:
   Remove shell script. Make compare of the test results inside the 
java-file.
   Also, I have fixed indentation and code style to be more Java-style.

Testing:
   Locally and JPRT.
   Verified that it still reproduces the original issue the regression 
test was made for.
