methods in JTD will be analysed (bugfix) #2

Before, methods would only be analysed (and mutants generated), if the a parameter shadows an instance variable. But a local variable can shadow an instance var as well.

And I'm not sure about the AssignmentExpression function. In my tests, it never had to change anything. Is it necessary?

DerBaer0, before my student and I check this request, can you be more clear?

Can you give an example scenario with a mutant that should be created that is not?
Can you identify yourself?

DerBaer0 commented 9 years ago

I use this simple Java program: https://gist.github.com/DerBaer0/0aa400abf29bc2d5b897 muJava produces 1 JTD mutant: Line 18: this.value = this.bar; => this.value = bar; I would expect more 3 mutants with the different "this.value"s replaced by "value".

I am a regular student, trying to use muJava for my thesis.
