Dag H. Wanvik commented on DERBY-3713:
--------------------------------------
I think so; the original author hasn't commented on Bryan's obervation, so
it's unclear if this is a bug at all and no repro exists.
> memory leak when insert rows into a table using
> org.apache.derby.jdbc.EmbeddedDriver
> -------------------------------------------------------------------------------------
>
> Key: DERBY-3713
> URL: https://issues.apache.org/jira/browse/DERBY-3713
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.4.1.3
> Environment: solaris and macos, jdk1.5
> Reporter: Peter Schi
>
> I downloaded the latest derby and I only modified the SimpleApp.java which
> came with the software under db-derby-10.4.1.3-bin/demo/programs/simple
> directory by inserting a larger string into the same table and I inserted the
> same data for 10000 times, just using the default driver which was
> org.apache.derby.jdbc.EmbeddedDriver
> I found out that there was memory leak, the size of used memory got increased
> and was about the same size of total data inserted into the table.
> For example, if 2MB size of data was inserted into the table, then the size
> of used memory was increased by 2MB as well.
> The memory leak still happened even if the database was shut down.
