Sql Developer 3.1 - Exporting a result set in xls generates and empty file
Ever since upgrading to the Production version SQL Developer 3.1 (3.1.07) it appears that there is an issue when attempting to export a result set as a .xls format.
If I attempt to export in .xls format, the exported file is an empty file (i,e no output). When I change the export type to txt, csv or xlsx the results are exported as expected.
This appears to be a bug introduced in the Production version as I was successfully able to perform these tasks on the various 3.1 EA releases.
Am I alone in this, have I misconfigured something or is this a bug?
