I found the problem. Here's a modified version of UnitCompiler.java (modified from the 2.5.0 codebase) which fixes it for my testcase; I'm going to run it through the full Farrago regression suite now.

Problem is that some walking-up-the-tree code is doing instanceof Java.BlockStatement where it should also be checking for Java.CatchClause. Some places were already checking for both. I added a method isBlocky and replaced the remaining ones, and that seems to fix it. Probably there are more to be fixed.

Fixed in 2.5.1, published NOW.
