Description

I decided to get an early jump on testing our application with the new 1.6 beta (and I was very curious about the speed improvements). It turns out I cannot deploy after upgrading to the 1.6-beta-1 version. All my groovy classes compiled fine previously, however now some of them fail with an exception like:

Caught: java.lang.ClassFormatError: Invalid method Code length 68630 in class file big

For example, I have attached file called big.groovy file which just returns a very large array (about 1900 or so integers). Using groovy.bat, this class works fine under 1.5.4, but fails with the ClassFormatError under 1.6-beta-1.

Even more interesting is the size of the class file. Using groovyc, compare the sizes of the produced class files:

Size of class file for 1.6-beta: 183,924
Size of class file for 1.5.4: 42,105

So there is roughly a 4 times increase in size of the produced class. I assume that has to do with the optimizations, right? Or is it something else?
