   I see several modules from the java area in the list of affected modules. If 
any of these creates `SingleMethod` instances and receives one from one of the 
modules you modified, they will not be `equals`. Consider a Method `Dummy#test` 
in the file `Dummy.java`, you create:
   
   `SingleMethod(file=Dummy.java, methodName=test, enclosingType=Dummy)`
   
   but the receiving module might create this:
   
   `SingleMethod(file=Dummy.java, methodName=test, enclosingType=null)`
   
   According to the implementation of `equals` these two are not equal anymore.
   
   This becomes even harder because the relationship between the filename and 
the enclosing type is only trivial for java, but not for other languages. PHP 
and Javascript for example have no hard connection between filename and 
embedded type, so they can't be derived from each other.
   
   For PHP for example the methodName is the combination of the type and the 
type. See here:
