svn commit: r432493 - /db/derby/code/trunk/java/drda/org/apache/derby/impl/drda/NetworkServerControlImpl.java

Log:
DERBY-1710: Unchecked casts from SQLException to EmbedSQLException
cause ClassCastException in NetworkServerControlImpl when running
Java SE 6

The attached patch makes NetworkServerControlImpl use
SQLException.getSQLState() instead of EmbedSQLException.getMessageId()
where possible. Where it is not possible, check that the exception is
EmbedSQLException before casting, and fall back to a more generic
approach if it is not.
