Oh, for a #define :)

There may be value in doing this, but what's the increase in class file
overhead? Every new class that gets created for these locks ends up as
another class file that has to be stored (takes up drive space) and has to
be loaded (takes up memory in the class loader). Ever additional class file
takes up at least 1K of space on Windows.
How many of these locks are we talking about?
I haven't counted, but I'd guess 10's rather than 100's based on what I
have found so far.
Each .class files created take up about 360 bytes in the JAR file. The
size in memory is obviously dependent upon the VM implementation but I
don't expect it to be onerous (in the IBM VME it will, by coincidence,
be very roughly the same number of bytes in memory).

Another variant is to use anonymous class without the name:
Object lock = new Object(){};
But the name by itself (RepositionLock) serves like a comment.
Yep -- I'm inclined to keep the meaningful name.
