Overview

Increasing and decreasing record size and deleting a record does not free memory correctly.

Description

Increasing and decreasing the size of a record by using the RecordStore.setRecord() method can increase memory consumption for the first time. If the increase/decrease is done for the same record in a loop, the size does not increase/decrease correctly in every iteration.

How to reproduce

Add a new record, increase its record size, and decrease it by using the following code lines:

recordstore.addRecord(new byte[100], 0, 100);
recordstore. setRecord(1, new byte[1000], 0, 1000);
recordstore. setRecord(1, new byte[100], 0, 1000);

Delete the record by using RecordStore.deleteRecord() method.

The available RecordStore size can be asked between these steps by using the RecordStore.getSizeAvailable() method.
