Previous MouseJoints are not getting destroyed when bodies overlap - screenshot - libgdx

Question

I am getting some weird some weird behaviour with my code.
My bodies with the same MASK and CATEGORY when overlapping and touchDragged, recreate the previous mouseJoints.
//collision
final short CATEGORY_PLAYER = 0x0001; // 0000000000000001 in binary
final short CATEGORY_SCENERY = 0x0004; // 0000000000000100 in binary
final short MASK_PLAYER = CATEGORY_SCENERY; // or ~CATEGORY_PLAYER
short MASK_SCENERY = -1;
Here is my MouseJoing implementation:
/**
* Creates the MouseJoint definition.
*
* #param body
* First body of the joint (i.e. ground, walls, etc.)
*/
private void createMouseJointDefinition(Body body) {
mouseJointDef = new MouseJointDef();
mouseJointDef.bodyA = body;
mouseJointDef.collideConnected = false;
mouseJointDef.maxForce = 500;
}
#Override
public boolean touchDown(int screenX, int screenY, int pointer, int button) {
/*
* Define a new QueryCallback. This callback will be used in
* world.QueryAABB method.
*/
QueryCallback queryCallback = new QueryCallback() {
#Override
public boolean reportFixture(Fixture fixture) {
boolean testResult;
/*
* If the hit point is inside the fixture of the body, create a
* new MouseJoint.
*/
if (testResult = fixture.testPoint(touchPosition.x,
touchPosition.y)) {
mouseJointDef.bodyB = fixture.getBody();
mouseJointDef.target.set(touchPosition.x, touchPosition.y);
mouseJoint = (MouseJoint) world.createJoint(mouseJointDef);
}
return testResult;
}
};
/* Translate camera point to world point */
camera.unproject(touchPosition.set(screenX, screenY, 0));
/*
* Query the world for all fixtures that potentially overlap the touched
* point.
*/
world.QueryAABB(queryCallback, touchPosition.x, touchPosition.y,
touchPosition.x, touchPosition.y);
return true;
}
#Override
public boolean touchUp(int screenX, int screenY, int pointer, int button) {
/* Whether the input was processed */
boolean processed = false;
/* If a MouseJoint is defined, destroy it */
if (mouseJoint != null) {
world.destroyJoint(mouseJoint);
mouseJoint = null;
processed = true;
}
return processed;
}
#Override
public boolean touchDragged(int screenX, int screenY, int pointer) {
/* Whether the input was processed */
boolean processed = false;
/*
* If a MouseJoint is defined, update its target with current position.
*/
if (mouseJoint != null) {
/* Translate camera point to world point */
camera.unproject(touchPosition.set(screenX, screenY, 0));
mouseJoint.setTarget(new Vector2(touchPosition.x, touchPosition.y));
}
return processed;
}
Thanks for your time....

Fixed by iterating all created jointsworld.getJoints(worldJoints);and destroying the old ones. .
