Attempts to upload IBM Rational Team Concert floating license results in the "CRJAZ1490E The upload did not complete in a reasonable amount of time" error seen on the JTS Screen.
The upload of the License file takes an unusually long time and then display the error message on the loading screen.
This is caused due to unsupported browsers being used for uploading the license jar file.
