Knut Anders Hatlen updated DERBY-1142:
--------------------------------------

Attached repro. With Derby 10.1.2.1 and Sun JVM 1.4.2,
OutOfMemoryError was thrown after about 80000 calls to
DatabaseMetaData.getCatalogs().
> Metadata calls leak memory
> --------------------------
>
> Key: DERBY-1142
> URL: http://issues.apache.org/jira/browse/DERBY-1142
> Project: Derby
> Type: Bug
> Components: JDBC
> Versions: 10.1.2.1, 10.2.0.0
> Reporter: Knut Anders Hatlen
> Priority: Minor
> Attachments: metadataloop.java
>
> When calling a DatabaseMetaData method that returns a ResultSet,
> memory is leaked. A loop like this (using the embedded driver)
> while (true) {
> ResultSet rs = dmd.getSchemas();
> rs.close();
> }
> will eventually cause an OutOfMemoryError.
