Knut Anders Hatlen resolved DERBY-493.
--------------------------------------
Resolution: Cannot Reproduce
I tried to reproduce this problem by executing the following code snippet:
Connection c =
DriverManager.getConnection("jdbc:derby:db;user=nosuchschema;create=true");
ResultSet rs = c.getMetaData().getProcedureColumns(null, "%", "%", "%");
while (rs.next());
rs.close();
It fails with "ERROR 42Y07: Schema 'NOSUCHSCHEMA' does not exist" on Derby 10.1
(tested with 10.1.1.0, 10.1.2.1 and 10.1.3.1). However it does not reproduce on
10.2.1.6 and higher, so I'm assuming the problem that's described here has been
fixed.
Resolving the issue.

> Key: DERBY-493
> URL: https://issues.apache.org/jira/browse/DERBY-493
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.1.1.0, 10.2.1.6
> Reporter: A B
> Labels: derby_triage10_5_2
>
> The SQLPROCEDURECOLS procedure that Derby defines internally to handle the
> DatabaseMetaData.getProcedureColumns() call (in JDBC) and the
> SQLProcedureColumns() call (in ODBC) will fail with "schema not found" error
> if it is called when "current schema" doesn't exist. This is a problem with
> Derby embedded, and thus can be seen from embedded mode, server mode (JDBC),
> and ODBC.
> None of the other metadata procedures have this problem; only
> SQLPROCEDURECOLS.
