I'm sure I've seen this issue reported before, but a search hasn't turned it up.
This appears to happen randomly, but once it starts it doesn't seem to stop ... at least for a while. I attempt to compile a class and compilation fails but produces no error explaining why. Here's an example:

The last two compilation errors repeat indefinitely (or at least until I've found and fixed the issue), but I can open the class in Studio, compile, and get the error information in the output panel every time. The compilation qualifiers are the same in both.
