Re: AST Transformation in Groovy 4.0.x VS 3.0.x

Just a long shot, but have you checked if this error might be due to a 
broken build or similar, i.e. class files being modified in parallel or 
source files having been modified while the build process was running ?
We see "ArrayIndexOutOfBoundsException: size==0" exceptions from time to 
time during IntelliJ Groovy builds, and the cause is typically as stated 
above. Building anew (sometimes rebuilding a module or the whole project 
is required) typically fixes these... (we had some which were actual 
bugs in the Groovy compiler, but these are very rare).

Cheers,
mg
