I did not manage to identify a standalone case, but it looks like if we have a case like below: public class A { ... public void m() { ... x() } } public class B { public void x() { ... } } public class C { ... } we sometimes get x as belonging to class C instead of B. The interesting part is that the invocation will go from A::m() to C::x(). This is a critical issue that stops us from using VerveineJ because the information is too unreliable.

I would really love to solve this problem. Like any other one for which you can provide me something to work on. I don't need to explain to you how difficult it is to solve a bug that occur from time to time whitout any concrete example that produce the error ... nicolas ----- Mail original -----

Comment #3 on issue 728 by tu...(a)tudorgirba.com: VerveineJ places methods in the wrong classes http://code.google.com/p/moose-technology/issues/detail?id=728 I will certainly not close it :).

I did not close it because I think it is irrelevant, but because without more information it is close to useless. As I said I would be more than happy to solve it. As for the example, I don't even ask for a simple one (although the simpler is definitely the better), I just need one example. Anyway, you know how it is ... nicolas ----- Mail original -----

can't you rename all things C1, C2, C3, ... m1, m2, m3, ... v1, v2, v3, ... and remove everything that appears to be unrelated (arithmetic expressions, I/O, conditions and loops) obfuscate it ...

However, we still have another case of misplaced methods that is still present. It is different than the one I sent you in that it seems to only involve super calls (while the other one was related to calls to a different class). Essentially, something like: public class A extends SomeClass { ... public void x() { super.m() } } leads to m() being placed in an unrelated class B. I suspect it is the same issue as the one you fixed only present in a different place. I am not sure if my description is clear enough. I will try again to reproduce on a smaller case study.

Updates: Status: Started Comment #7 on issue 728 by tudor.gi...(a)gmail.com: VerveineJ places methods in the wrong classes http://code.google.com/p/moose-technology/issues/detail?id=728 Hmm, I just tried. First, I fixed the shell script (verveinej.sh) to collect the jars automatically from the lib folder. Then I removed the obsolete jars. But, still, if I run the following experiment, I get 575 potentially problematic methods: - download ArgoUML 0.32 from: http://argouml-downloads.tigris.org/argouml-0.32/ - parse, load in Moose, and then execute: (MooseModel root allModels first allMethods select: [:each | each sourceAnchor isNil and: [ each parentType sourceAnchor notNil and: [ '<Initializer>' ~= each name and: [ each name ~= each parentType name ]]]]) openInMoose Am I doing something wrong?

New subject: Issue 728 in moose-technology: VerveineJ places methods in the wrong classes

what I did: - download ArgoUML-0.32-src.tar.gz (sources of ArgoUML) from the web site you gave - download ArgoUML-0.32-libs.tar.gz (libraries needed by ArgoUML) from the web site you gave - update verveinej to get your new shell script - rm -f output.mse - create MSE file:"verveinej.sh -autocp ArgoUML-0.32-libs ArgoUML-0.32-src" - load MSE in Moose panel - ran your script in workspace When calling verveineJ, "-autocp ArgoUML-0.32-libs" is important. Without it, JDT is not able to resolve a lot of types names, and as a consequence, a lot of source methods that use these types (e.g. as parameter type). And without JDT's name resolution, verveineJ is not able to link a method call to a method declaration. With the autocp, I found 13 methods with problems. Without it, I found 473 (or something like that) methods with problems. Not your 575 ones, but closer to it. No idea how we can get so different results with the same data and program !!! nicolas ----- Mail original -----

Thanks. Indeed, it is strange. Btw, I am on a Mac OS X Lion. I will try again and get back to you later. But, coming back to the issue, the goal of the script is to provide a set of possible methods that are misplaced (that is methods that should appear in another class than where they are actually defined). The issue is that if we have the source for the class, it means we should have parsed it and have the proper information about its methods. So, how could then methods appear inside without source code? Cheers, Doru On 1 Nov 2011, at 10:35, Nicolas Anquetil wrote:

Yes it does seem strange, and it took me a while to accept it. The point is that, in Java, you can have different methods with the same name and different parameters. So, without a clear handle on the type of all parameters, you cannot decide for sure that a method call is the same as a method declaration. Another point is that JDT is made to work in an IDE, with incomplete code. That's why, even with the source declaration of the method, JDT does not link it to its calls unless it could resolve all the parameters' types. That's why it is also important to have all the needed libraries when parsing with verveineJ nicolas ----- Mail original -----
