Misys might be open source now according to this press release only it seems that they forgot to actually release the source according to Matt Asay: ‘…What he failed to mention was the license, the location (to download the source), and to give any details on how to get involved.

You won’t find the project on Sourceforge. Codehaus doesn’t have it, either. Nor does Misys on its own website, apparently.

What benefits will Misys derive from open source if it doesn’t engage an external development community?…’
