This is an analysis done in 2004, more or less out of curiosity.  Some of the results seemed pretty interesting to me, such as: Two solutions that lack an event horizon. One solution, close to Schwarzchild's solution outside of the black hole, but with a more rapid approach to the vacuum at large distances.  A second solution that displays harmonic oscillator binding at large distances and close to Schwarzchild's inside of the black hole.  It could be relevant to Quark confinement.

​

There are several issues that it suggests for more analysis.,
