[GROOVY-11206] Concatenated strings not treated as compile-time constants

Description

This problem was marked fixed with GROOVY-9855, but I'm seeing (a variant of?) it again:

@Grab(Example.CONSTANT)
// ^ The value for annotation attribute Grab.value must be a constant expression
class Example {
  public static final String GROUP = 'asdf'
  public static final String CONSTANT = GROUP + ':asdf:0.1'
}

In case it's relevant, the non-minimal case involves a statically imported constant from another class:

class MyController {
  public static final String PARAM_OWNER = 'filter[' + REL_OWNER + ']'

  @GetMapping(params = PARAM_OWNER)
  // ^ Expected 'PARAM_OWNER' to be an inline constant of type java.lang.String not a field expression in @org.springframework.web.bind.annotation.GetMapping
  ...
}
