Houx Zhang updated DERBY-4443:
------------------------------
Attachment: DERBY-4443-6-tmp.patch
Hello, I have provided DERBY-4443-6-tmp.patch.
private static void rollBackAndThrowSQLException(Connection conn,
SQLException se) throws SQLException {
try {
conn.rollback();
} catch (SQLException e) {
se.setNextException(e);
}
StandardException ste = StandardException.newException(
se.getSQLState(), (Throwable)se);
SQLException sqle = new SQLException((Throwable)ste); //this line can
not pass compilation
throw sqle;
}
In rollBackAndThrowSQLException() of this patch, SQLException has been wrapped
in StandardException, which is wrapped in another SQLException. However, the
patch can not pass compilation, and says "constructor
SQLException(java.lang.Throwable) can not be found". I'm puzzled about it.
Please give an advice, thanks!
