Daniel John Debrunner commented on DERBY-766:
---------------------------------------------
I don't have a 10.1 codeline handy but this error:
java.lang.NoSuchMethodException:
org.apache.derby.iapi.sql.execute.ResultSetFactory.getNestedLoopJoinResultSet(org.apach
e.derby.iapi.sql.execute.ResultSetFactory,
org.apache.derby.iapi.sql.execute.NoPutResultSet, int, org.apache.derby.iapi.
sql.execute.NoPutResultSet, int,
org.apache.derby.iapi.services.loader.GeneratedMethod, int, boolean, boolean,
double, d
says that it's looking for a getNestedLoopJoinResultSet() method with a
ResultSetFactory as its first argument. I don't think any of the ResultSets
constructors take a ResultSetFactory argument.
The error most likely is the wrong number of arguments (one too many) are
being passed in to the invoke method call so that it is picking up the
ResultSetFactory intended for another ResultSet creation.
