I've been reviewing this one again. The bit that confuses me is that the
menu_jsp.class file contains the latest version but clearly the version loaded
by the class loader is an older version. The timestamp checks that take place
are in milliseconds and a quick text shows that there is reasonably fine
granularity with these.

It does look like a race condition but one that I can't figure out given the
current code. There have been changes to Jasper post 4.1.x (increased
synchronisation, switch to the Eclipse compiler, improved dependency checking)
and I don't recall any similar issues in 5.5.x onwards.

Given the above, it isn't very satisfactory but I am going to resolve this as
WONTFIX an the assumption that this was a 4.1.x bug that was fixed in 5.5.x
onwards by the various changes.
