Description

Compilation of this statement fails with a NullPointerException:

insert into t select x from (select ? from t) s

It should fail, but not with a NullPointerException. The expected error is:

ERROR 42X34: There is a ? parameter in the select list. This is not allowed.

I found this issue when testing the fix for DERBY-4671. It is not the same issue, since DERBY-4671 was a regression in 10.6.1, and this issue has been there for a long time (I've only tested back to 10.2.2.0, but it may have existed even before that).
