A DESCRIPTION OF THE PROBLEM :
sun.jdbc.odbc.JdbcOdbcResultSet#getString returns trailing nulls

See source code below

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See source code below

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
myRs.getString( STRING1): "Here are only 16 + 16 more chars"
ACTUAL -
myRs.getString( STRING1): "Here are only 16 + 16 more chars\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000"
