This is indeed the way to force a fresh build, via that indirection to 
build Isabelle/jEdit.  See also the recent addition here 

I've managed to reduce the chances of bad Isabelle/Scala self-compilation 
a little bit recently, but it is not 100% bullet-proof.  In particular it 
is not thread-safe.  (This is not relevant for official releases, only for 
building repository snapshots.)
