Tobias Schulte commented on JEXL-101:
-------------------------------------
I wanted to give another example, that shows the real problem, but it seems
that java.util.Formatter, where i thought would be a problem, itself is not
consistent.
{code:java}formatter.format("%1$s", null);{code}
outputs "null"
{code:java}formatter.format("%1$s %2$s %3$s", null);{code}
outputs "null null null" (but should throw a MissingFormatArgumentException, at
least if I understand the documentation correctly)
but
{code:java}formatter.format("%1$s %2$s %3$s", null, null);{code}
throws a MissingFormatArgumentException.
Since we are using formatters I thought your optimization in MethodExecutor
would cause MissingFormatArgumentExceptions, which it does not seem to do.
But nontheless I would expect callMixed(1, null) to be equal to callMixed(1,
new Integer[]{null}).
