Wrong DirectionalLightShadow effect

Troubleshooting General Help

i get a wrong DirectionalLightShadow effect with a model(a swimming fish) playing skeleton animation.
during swimming animation process, there are twinkling sticks poking out of the fish shadow’s mouth and top fin at some particular frames.

the screen shot is here below

i use soft CompareMode in AbstractShadowRenderer, because my hardware seems do not support sampler2DShadow.

i setup this shadow effect by
[java]
private void setupShadow() {
dlsr = new DirectionalLightShadowRenderer(assetManager, 512, 1);
dlsr.setLight(sun);
dlsr.setLambda(0.55f);
dlsr.setShadowIntensity(0.6f);
dlsr.setEdgeFilteringMode(EdgeFilteringMode.Nearest);
//dlsr.displayDebug();
viewPort.addProcessor(dlsr);

    dlsf = new DirectionalLightShadowFilter(assetManager, 512, 1);
    dlsf.setLight(sun);
    dlsf.setLambda(0.55f);
    dlsf.setShadowIntensity(0.6f);
    dlsf.setEdgeFilteringMode(EdgeFilteringMode.Nearest);
    dlsf.setEnabled(false);

    FilterPostProcessor fpp = new FilterPostProcessor(assetManager);
    fpp.addFilter(dlsf);

    viewPort.addProcessor(fpp);
    
    rootNode.setShadowMode(ShadowMode.Off);
    fish.setShadowMode(ShadowMode.Cast);
    ground.setShadowMode(ShadowMode.Receive);
}

[/java]

the DirectionalLight is defined as below
[java]
sun = new DirectionalLight();
sun.setDirection(new Vector3f(-0.1f, -0.2f, -1.0f).normalizeLocal());
rootNode.addLight(sun);
[/java]

the fish model and its animation is loaded like
[java]
fish = assetManager.loadModel(“fish.mesh.xml”);
fish.scale(5.0f, 3.0f, 3.0f);
rootNode.attachChild(fish);

    control = fish.getControl(AnimControl.class);
    channel = control.createChannel();
    channel.setAnim("swim");
    channel.setSpeed(0.6f);
    channel.setLoopMode(LoopMode.Loop);

[/java]

I may not be the best suited to answer this question but I believe someone might need a bit more information in order to further assist with the problem.
Is the wrong effect you are speaking of the stick poking out of the fish shadow’s mouth and top fin in the screen shots?

I’m also just shooting in the dark here but how is the fish animation set up? ( As in what type of model is it)
