[ http://issues.apache.org/jira/browse/DERBY-1142?page=all ]
Daniel John Debrunner updated DERBY-1142:
-----------------------------------------
Attachment: 1142_close_single_use_activations_draft.txt
Draft patch that closes an EmbedResultSet's single use activation when the
result set is closed. Previously the activations' close would have been delayed
until after the EmbedResultSet was garbage collected and some activilty occured
in the connection that caused the list of activations to be scanned. Comment
needs some comments before being applied.
> 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
> Assignee: Daniel John Debrunner
> Priority: Minor
> Attachments: 1142_close_single_use_activations_draft.txt, 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.
