Description

I've got a grails app with service classes that implement GroovyInterceptable:

class customerService implements GroovyInterceptable { 
    private List<Customer> customers 
    def invokeMethod(String name, args) { 
        log.debug "=======>INVOKING method [$name] with args:$args" 
    } 
    void foo() { 
        customers.each { doSomething(it) } 
    } 
    void doSomething(Customer cust) {
        log.debug "doSomething invoked with $cust"
    } 
} 

If I call foo() or doSomething() directly from another class, the invokeMethod gets called like it is supposed to. However, when foo() calls doSomething(), that call is not intercepted in invokeMethod.

If I change from

customers.each { doSomething(it) }

to

for(Customer cust: customers) { doSomething(cust) }

then the invokeMethod gets called just fine.

There appears to be an ExpandoMetaClass bug that prevents closures and GroovyInterceptable from working together.
