Description
All the information can be found on this forum post.
Whenever the FPP is initialized + contains a non-depth-texture-required filter and a depth-texture-required filter is added, it throws:
java.lang.UnsupportedOperationException: FrameBuffer already initialized.
at com.jme3.texture.FrameBuffer.setDepthTexture(FrameBuffer.java:473)

Research direction
Start with FilterPostProcessor.addFilter and initFilter, then inspect FrameBuffer.setDepthTexture at the stack-trace locations. Reproduce the failure by initializing the FPP with a non-depth-texture-required filter before adding a depth-texture-required filter. Done means this sequence no longer throws the FrameBuffer already initialized exception.
