Map access is given higher precedence when trying to access fields/properties in classes which implement java.util.Map or extend java.util.HashMap or java.util.Properties

import groovy.util.logging.*

[new Test1(), new Test2(), new Test3()].each {
    runTest(it)
}

def runTest (obj) {
    try {
         obj.test()
         obj.method()
         println "${obj.getClass()} success"
    }
    catch (e) {
         println "${obj.getClass()} failed $e"
    }
}

//   classes

@Log4j
class Test1 {
    def test () {
         println '============================='
         println 'testing plain Groovy class'
         println "testing class [${this.getClass().getSimpleName()}]"
    }
    def method () {
        log.debug 'method called, not in closure'
        ['a', 'b', 'c'].each {
            log.debug "inside closure [$it]"
        }
    }
}

@Log4j
class Test2 extends BaseClass {
    def test () {
         println '============================='
         println 'testing Groovy class that extends another Groovy class'
         println "testing class [${this.getClass().getSimpleName()}]"
    }
    def method () {
        log.debug 'method called, not in closure'
        ['a', 'b', 'c'].each {
            log.debug "inside closure [$it]"
        }
    }
