    Preondition Violations
    Expression ex.printStackTrace() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression ex.printStackTrace() is a void method call, and thus it cannot be parameterized
    Expression cache.clear() is a void method call, and thus it cannot be parameterized
    Expression ex cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Type java.lang.Exception of variable ex does not match with type org.columba.core.io.StreamCache of variable cache
    • Make classes java.lang.Exception and org.columba.core.io.StreamCache extend a common superclass
