SqlException returned if no schema matches

Running schemaSpy with either no schema defined or an invalid schema definition results in SqlException.

For example:

<java jar="${lib}/schemaSpy_3.1.1.jar"
fork="true">
<arg line="-t udbt4"/>
<arg line="-host ${db.host}"/>
<arg line="-port ${db.port}"/>
<arg line="-db ${database}"/>
<arg line="-u ${db.userid}"/>
<arg line="-p ${db.password}"/>
<arg line="-s NONEXISTENT"/>
<arg line="-cp ${DB2_LIB}/db2jcc.jar:${DB2_LIB}/db2jcc_license_cu.jar"/>
<arg line="-o ${reports.data.model.dir}"/>
</java>

results in:
