Saurabh Vyas commented on DERBY-2260:
-------------------------------------
I have a question regarding assertFalse(rs.wasNull()) in testGetTypeInfo()
method in DatabaseMetaDataTest.java. After one 'assertEquals' for precision,
there is an 'assertFalse'. Why this assert is required? This assert was failing
for me (after I had added case for XML data type for precision).
Did I missed any thing in the test ?
