Cannot call closure element of map as method in sandbox

XMLWordPrintable

      Normal Groovy allows Closure elements of Map instances to be called using method call syntax. That is, the following is valid Groovy:

      def m = [ f: { return 'hello' } ]
println m.f()

      However, this is rejected by the sandbox:

      groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.f() is applicable for argument types: () values: []
Possible solutions: is(java.lang.Object), find(), any(), get(java.lang.Object), get(java.lang.Object), get(java.lang.Object)

      Note that the more explicit (m.f)() and m['f']() work just fine.
