Description

in short: calling the ++ operator on an Integer does not increment the value when using static compilation.

Example:

class IntegerIncrementStaticCompilationBug {

    Integer index = 0

    @groovy.transform.CompileStatic
    void increment() {
	index++
    }
}

def b = new IntegerIncrementStaticCompilationBug()
b.increment(); b.increment(); b.increment()

println b.index

This script should print "3", but it prints "0".
Works find when CompileStatic annotation is removed.
