Yes, the JDT parser does a pretty good job at error recovery, so
they get an AST to work with in spite of a pretty wide variety of
syntax errors.

We're actually working on a semi-automatic error recovery mechanism
for LPG, but in the meantime, you'll need to do it more manually.
I'd suggest posting a query for help on the LPG sourceforge site.

If you're not using LPG, consult your parser generator manuals for
hints on how to get the generated parser to recover. Most parser
generators provide some form of error recovery mechanism.
