XmlReportOutputter not safe
---------------------------
Key: IVY-605
URL: https://issues.apache.org/jira/browse/IVY-605
Project: Ivy
Issue Type: Bug
Components: Core
Reporter: Jean-Baptiste Quenot
When issuing several "resolve" task in parallel on several projects having the
*same* Ivy file, it may happen that the generated XML reports in ivy cache are
overwritten. And thus at a given moment in time, this file may appear empty,
as FileOutputStream overwrites the destination directly. When using the
"report" task (also in parallel), this leads to the following error:
{noformat}
