Hi @codeconsole — the flaky `ConcurrentModificationException` in
`GroovyLanguageServerTest` (e.g.
`publishDiagnosticsIncludeVersionAndClearRemovedUris`) should be fixed on
`master` by #3094 / GROOVY-12565 (`CopyOnWriteArrayList`). This tip looks like
it predates that merge, so CI can still hit the old failure.
Could you please rebase onto current `master` (or merge `master`) when you
have a moment, so we can re-check with the fix included? Thanks!

> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 5.0.8, 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {code:groovy}
> @groovy.transform.CompileStatic
> class C {

> aload_0
> {code}
> In a static method or static initializer, {{this}} is the class object, and
> the type checker accepts a call to a method of {{Class}} without a receiver,
> like {{getName()}}, {{getSimpleName()}} or {{toString()}}. The static
> invocation writer treats the method as one of an enclosing class and loads
> {{Class.this}}, local variable 0, which does not exist in a static method.
> Methods of {{Object}}, such as {{hashCode()}}, work. 4.0.33 returns {{'C'}},
> as dynamic Groovy and an explicit {{this.getSimpleName()}} do.
