-----------------------------
> Allow optimized array access in static compiled code with indy

> Key: GROOVY-7239
> URL: https://issues.apache.org/jira/browse/GROOVY-7239
> Project: Groovy
> Issue Type: Improvement
> Reporter: Jochen Theodorou

> Fix For: 2.5.0-alpha-1

>
> to perform a intArray[i] access Groovy usually goes through an either fully
> dynamic path, or a special method in BytecodeInterface8. This has to be done,
> because of the semantics of allowing a negative array index. This results in
> a speed penalty even for static compiled code.
> The improvement here is to use invokedynamic to perform the array access
> instead. The semantics will stay equal, but if a constant call site can be
> used performance will be on par with Java. This of course works only if the
> callsite will use static information. This means this change is suitable only
> for @CompileStatic for now.
> This change also implies no null check for the array, causing an NPE is the
> array is null. But this is in line with current behavior in static compilation
