FULL PRODUCT VERSION :
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Client VM (build 25.5-b02, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Windows 8
A DESCRIPTION OF THE PROBLEM :
JDK 8 started to generate incorrect LOCALVARIABLE info, because of that debugger does not show local variables in some cases, see http://youtrack.jetbrains.com/issue/IDEA-126287
REGRESSION. Last worked in version 7u51
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
compile and stop on a breakpoint in the provided source code
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
j is available as a local variable
ACTUAL -
not available
REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Use jdk 7, it generates correct LOCALVARIABLE info
