I'm trying to delete an object when a collision happens. I have put the following code in the render method of the object so it would be outside of the physics calculations.

public void render(SpriteBatch spriteBatch) {
    // some other code...
    body.setActive(false);
    body.getWorld().destroyBody(body);

But I'm getting an run-time error which crashes the JVM and shows,

AL lib: alc_cleanup: 1 device not closed

Assertion failed!

Program: C:\Program Files\Java\jre6\bin\javaw.exe File: /var/lib/hudson/jobs/libgdx-git/workspace/gdx/jni/Box2D/Dynamics/b2World.cpp, Line 133

Expression: m_bodyCount > 0

Can anyone help me here?
