> Hello devs,
> Calling MethodUtils.getMatchingAccessibleMethod with the arguments:
>  *  cls is the class of `java.nio.file.Files`
>  * methodName is the string `exists`
>  * parameterTypes is an array with the class of `java.nio.file.Path`
> triggers a NullPointerException:
> {code:java}
> Cannot invoke "java.lang.Class.getName()" because the return value of "java.lang.Class.getSuperclass()" is null
>     at org.apache.commons.lang3.reflect.MethodUtils.getMatchingAccessibleMethod(MethodUtils.java:354)
> {code}
> I suspect it is this line: https://github.com/apache/commons-lang/blob/master/src/main/java/org/apache/commons/lang3/reflect/MethodUtils.java#L352 that is buggy
> In particular, I suspect the problem is that `java.nio.file.Path` is an interface which lacks a super class. 
> I am happy to provide more information if needed.
> Thanks for making this library. It has been very useful to us.
