I have a set of web services that are intercepted by an Aspect with @AfterThrowing. The implementations of the web services are done in Kotlin, but it is based on generated Java code.

So I have a Java interface, and a Kotlin class implementing the interface. When the code throws I want to generically throw the defined fault in the Java interface instead (SomeFault):

public SomeResponseType methodName() throws SomeFault

If everything was in Java it could be done rather easily like this:

MethodSignature methodSignature = (MethodSignature) joinPoint.getStaticPart().getSignature();

Class<? extends Exception> declaredExceptions = methodSignature.getExceptionTypes();

...and then just execute the constructor of declaredExceptions[0]

But when I do something similar in Kotlin it seems like I can't find the exceptions declared in the Java interface:

val declaredExceptions = methodSignature.exceptionTypes

... gives me an empty list

question: How can I find the Exceptions declared in a java interface when intercepting a Kotlin class implementing that interface?

Found a solution based on JBs comment:

Class.forName(methodSignature.declaringType.genericInterfaces[0].typeName).declaredMethods

.filter { method -> method.name == methodSignature.name }

.forEach { method -> method.exceptionTypes[0] <executed>}
