The original project seems to be dual licensed (MIT/LGPL) as stated on the sourceforge page:

The original CVS repo contains reference to the GPL (in the file COPYING) which I believe was let in the repo but seems not to reflect authors updated views... see the website ((LGPL/MIT) or comments in sources or the website:

With an exception of the file Base64EncodingOutputBuffer.java which refers to Apache License 2.0.
Not a lawyer, but I guess being clear on that is important. So keeping a LICENSE.md with either the the LGPLv2 or MIT (keeping copyright to Jost Boekemeier) should be included in the project.
Anyone on this ?
