> Key: GROOVY-11439

> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Reporter: Thodoris Sotiropoulos
> Priority: Minor
> Labels: groovy
>
> I am not sure if this is an expected behavior or not, but a lambda expression
> is assignable to java.io.InputStream
>
> {code:java}
> class Test {
> public static void main(String[] args) {
> java.io.InputStream x = (int p, int p2) -> p;
> System.out.println(x.read());
> }
> } {code}
> h3. Actual behavior
> The code compiles, but I get the following exception at runtime
> {code:java}
> Exception in thread "main" groovy.lang.MissingMethodException: No signature
> of method: Test$_main_closure1.doCall() is applicable for argument types: ()
> values: []
> Possible solutions: doCall(int, int), isCase(java.lang.Object),
> isCase(java.lang.Object), findAll(), findAll(), findAll(groovy.lang.Closure)
> at
> org.codehaus.groovy.runtime.metaclass.ClosureMetaClass.invokeMethod(ClosureMetaClass.java:259)
> at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1006)
> at groovy.lang.Closure.call(Closure.java:452)
> at InputStream1_groovyProxy.read(Unknown Source)
> at Test.main(test.groovy:4) {code}
> h3. Expected behavior
> The code should have been rejected.
