------------------------------------------
Summary: 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
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.
