Detailed Description

The class detects jumps which bypass local variables declaration: goto L; int a; L:

This is simplified version of JumpScopeChecker. Primary differences:

• Detects only jumps into the scope local variables.
• Does not detect jumps out of the scope of local variables.
• Not limited to variables with initializers, JumpScopeChecker is limited.
