Just to confirm my hypothesis, I decided to temporarily rollback to java 7 update 40 and this fixed the problem. The "ConvertTo-UcsCmdlet" cmdlet found the log in the .ucsm directory and properly generated a cmdlet after I made a change in the GUI.
When I then upgraded back to java 7 update 45 the "ConvertTo-UcsCmdlet" broke again.
So for sure this is a java 7 update 45 related problem.
