Has anyone come accross this jitter java error?

    In one of my projects I am getting very irregularly following error:
    jit_java_jitobj_new: error trying to register object
    All I do with jitter in java is to create initially a couple of JitterMatrix object, using something like
    jm[h] = new JitterMatrix(h + matrixName, 13, "float32", new int[] {coord[0].length, 1 });
    Afterwards I resize the matrices and send them to several jit.gl.mesh objects. This happens every frame.
    For resizing the matrices I use something similar to:
    jm[h].setDim(new int[] { coord[0].length, 1 })
    Any idea?

      Hi Mark,
      This looks like a problem in our object registration code where we
      may be failing in the instance we try to register objects with the
      same name or object pointer before they have been garbage collected.
      The first solution would be to only create these matrices once. this
      will be noticeably more efficient than creating every frame. However
      if you need to create these matrices each frame, or dynamically, I
      would recommend using the freepeer() method on JitterMatrix. This
      will also save you some memory usage bloat that can happen as the GC
      waits to collect objects.
      Let us know if you still have problems, and please provide a simple
      but complete example which illustrates your problem with detailed
      platform and software version info.

      Hi Joshua,
      thanks for your advise. Actually the way I did it with resizing the matrix using jm.setDim() works now fine without causing any errors.
      I think the mentioned errors mainly occur when using too frequently the constructor JitterMatrix(java.lang.String name) to resize matrices within Java.
      Cheers
