040722, 1.5.0 b58. It seems that annotations for
Java parser errors are no longer displayed in the
source editor, at least in the cases I have tried.
Not sure how long this has been broken but I think
for a while.

I often notice that code completion or Fix Imports
is totally broken for a while and finally realize
(after trying to compile) that I have some syntax
error (missing '}', 'extends' in place of
'implements', etc.) that was never highlighted.
Even typing in something totally bogus, e.g.
adding a line

   xxx

to a method in an otherwise compilable source,
produces no error annotation.

These days I mostly notice if I have a syntax
error in my source because some features quietly
stop working, I hear a lot of unexplained disk
activity, and my log fills up with messages such as

  (source unavailable)
