Paul King commented on GROOVY-9702:
-----------------------------------
Merged for Groovy 4. [~emilles] Would something like
https://github.com/apache/groovy/pull/1356 work for GROOVY_3_0_X (and
potentially GROOVY_2_5_X). I agree that runtime seems unlikely to be needed but
just exploring whether we can avoid the breaking change on a point release.
> ASTTest annotation has runtime retention and transform removes required

> Key: GROOVY-9702
> URL: https://issues.apache.org/jira/browse/GROOVY-9702
> Project: Groovy
> Issue Type: Bug
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Labels: breaking
> Time Spent: 40m
> Remaining Estimate: 0h

> Consider the following:
> {code:groovy}
> import groovy.transform.*
> import org.codehaus.groovy.ast.*
> import static org.codehaus.groovy.transform.stc.StaticTypesMarker.*
> class C {
> void m() {
> def that = this;
> { ->
> @ASTTest(phase=INSTRUCTION_SELECTION, value={
> ClassNode type = node.getNodeMetaData(INFERRED_TYPE)
> assert type?.name == 'C'
> })
> def ref = getThisObject()
> assert ref == that
> }()
> }
> }
> {code}
> This is a typical use of {{@ASTTest}}. When compiled, the test annotation is
> retained in the class file, which is unnecessary. When the transform class
> runs, it removes the "value" member from the AST, which is causing compiler
> errors down the line when {{ExtendedVerifier}} runs {{AnnotationVisitor}}.
> Also, the variable scope of the test closure is still connected to the class
> and module, so code completion is making proposals for class members which
> will not be there at run-time.
> This was originally investigated from the IDE side (see linked issue).
