File stream not closed after fetching binary in core storage

Inputstream for a source file gets open, but never closed. Below is the code fragment:

package org.nuxeo.ecm.core.storage.sql.coremodel;
......
public class SQLContentProperty extends SQLComplexProperty {
......

@Override
public void setValue(Object value) throws DocumentException {
.......
InputStream stream;
try

{ stream = blob.getStream(); }

catch (IOException e)

{ throw new DocumentException(e); }

.......
}
