Description

parameter.metaClass returns different result when parameter type is "Class<?> parameter" compared to when type is "Class parameter"

Here is example code for Groovy console to reproduce the problem:

class ShowMcDynamic {
  MetaClass findMc(Class someClass) {
      someClass.metaClass
  }
  MetaClass findMcWithGenericsParam(Class<?> someClass) {
      someClass.metaClass
  }
}
def mcByDynamic = new ShowMcDynamic().findMc(String)
def mcByDynamic2 = new ShowMcDynamic().findMcWithGenericsParam(String)
assert mcByDynamic.theClass==String
assert mcByDynamic2.theClass==String

@groovy.transform.CompileStatic
class ShowMcStatic {
  MetaClass findMc(Class someClass) {
      someClass.metaClass
  }
  MetaClass findMcWithGenericsParam(Class<?> someClass) {
      someClass.metaClass
  }
}
def mcByStatic = new ShowMcStatic().findMc(String)
def mcByStatic2 = new ShowMcStatic().findMcWithGenericsParam(String)
assert mcByStatic.theClass==String
assert mcByStatic2.theClass==String
