Hylke van der Schaaf commented on LANG-1789:
--------------------------------------------
Simplest fix is probably adding a _private static nullSafeGetClassName_ method.
> NPE when generating NoSuchMethodException
> -----------------------------------------
>
> Key: LANG-1789
> URL: https://issues.apache.org/jira/browse/LANG-1789
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.reflect.*
> Affects Versions: 3.19.0
> Reporter: Hylke van der Schaaf
> Priority: Major
>
> When calling MethodUtils.invokeMethod, on an instance that does not have the
> requested Method, a NoSuchMethodException should be called.
> But, when one of the parameters to be passed to the method is Null, a
> NullPointerException is thrown when trying to create the
> NoSuchMethodException.
> This is because one of the entries in the parameterTypes method is now null,
> and thus the call to getClass on this parameter fails.
> Trace:
> {code:java}
> Exception in thread "JavaFX Application Thread" java.lang.NullPointerException
