AttributeError: 'MethodCallExpr' object has no attribute 'add_bang'

[martinezmatias]

Hello
I have followed the instructions you mention for running the jsketch scripts.
I had an error when I executed the example you wrote and the test cases:
For example, the execution of:
./jsk.sh test/new_ast/Construct.java

produces this error:

AttributeError: 'MethodCallExpr' object has no attribute 'add_bang'

Here the complete log:
