                 Key: GROOVY-10040
                 URL: https://issues.apache.org/jira/browse/GROOVY-10040
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 3.0.7
         Environment: Groovy 3.0.7
            Reporter: Marcin Zajaczkowski


I've bumped into that problem writing regression tests for using 
@AnnotationCollector in Spock to achieve meta-annotation support. A custom 
annotation accepting Clusure is problematic with @AnnotationCollector. It 
compiles file with groovyc, but not with ClassLoader (which is used by Spock's 
EmbeddedSpecCompiler).

The problem can be simply reproduced with `GroovyClassLoader`:
{code:java}
import groovy.transform.AnnotationCollector
class CustomCompiler {
final GroovyClassLoader loader = new GroovyClassLoader(getClass().classLoader)
static void main(String[] args) {
  new CustomCompiler().compile()
}
void compile() {
  loader.clearCache()
  Class clazz = loader.parseClass("""
//@${CustomCompiler.class.packageName}.RetryCustom //works fine
@${CustomCompiler.class.packageName}.MetaCustom 
//MultipleCompilationErrorsException exception
class Foo {
 void foo() {
 }
}
""")
  assert clazz
  }
}
@RetryCustom(1)
@RequiresCustom({ 1 == 1 })
@AnnotationCollector
@interface MetaCustom {
}
@interface RequiresCustom {
  Class<? extends Closure> value()
}
@interface RetryCustom {
  int value()
}
{code}
which results in:
{code:java}
Exception in thread "main" 
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

If it really happens only with `GroovyClassLoader`,it is a minor problem. 
However, I believe, I might have observed that occasionally while compiling 
with Idea 2020.3 (but I'm not able to reproduce it right now and I might 
confuse parameters).
