I tried switiching to 3.1M4 from M2 but started getting an 
'Internal compiler error' on one particular .java file. Everything 
is working properly in M2. Eclipse logs the following stacktrace 
everytime I try to compile my code.

-----------------------------------

 The concerned java file has 7.5k lines of code. I haven't been able to
 isolate the bug to a smaller piece of code.
