Summary0006723: [Wrapping JAVA of VTK] Bug with methods containing character '_'
DescriptionThe JNI library replace all "_" substrings in function names by "_1" and the parser of VTK doesn't do this so this error occurs :

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: vtk.vtkSelection.PROCESS_ID_36()J
        at vtk.vtkSelection.PROCESS_ID_36(Native Method)
        at vtk.vtkSelection.PROCESS_ID(vtkSelection.java:471)
        at testvtk.CascadeActorManager.selectOnSurface(CascadeActorManager.java:142)

        at java.awt.EventDispatchThread.run(EventDispatchThread.java:121)
BUILD STOPPED (total time: 12 seconds)

Because the real name expected by the JNI is vtk.vtkSelection.PROCESS_1ID_36 and not vtk.vtkSelection.PROCESS_ID_36. This is a program that can cause this :

import vtk.vtkSelection;

public class BugPROPID
{
      static
  {
    System.out.println(System.getProperty("java.library.path"));
    System.loadLibrary("vtkCommonJava");
    System.loadLibrary("vtkFilteringJava");
    System.loadLibrary("vtkIOJava");
    System.loadLibrary("vtkImagingJava");
    System.loadLibrary("vtkGraphicsJava");
    System.loadLibrary("vtkRenderingJava");
  }
  public static void main(String[] args)
  {
            vtkSelection selection = new vtkSelection();
            System.out.println("TEST : " + selection.PROP_ID());
  }
}

I have made a patch to fix it (it add '1' after all '_' in name methods and name classes).
TagsNo tags attached.

 The severity of this bug should be changed to "crash".

 Hi there, explanations about JNI name mangling can be found at
  http://java.sun.com/javase/6/docs/technotes/guides/jni/spec/design.html#wp133 [^]
So the fix is quite trivial, as reported by julianibarz, underscores
have to be replaced by "_1" in class and method names.
Since VTK class names contain no underscore, I propose a less
intrusive patch escapeMethodNameJava.patch to deal only with
method names, maybe you will like it more? This patch is very
safe, it is pretty obvious that nothing changes when method
name does not contain an underscore.
