Cause

JavaMelody 1.50 is incompatible with Stash 2.12.0 breaking the project and repository creation. For previous versions of Stash, JavaMelody incompatibility is not known.

Resolution

Remove JavaMelody from the Stash installation.

If by any chance this fails, the same installer version of Stash can be unpacked and Stash can be started from that installation directory (make sure to port any modifications from the previous installation directory), after pointing it to the original Stash home directory.
