1.8.0_151

ADDITIONAL OS VERSION INFORMATION :
windows version 10.0.15063

EXTRA RELEVANT SYSTEM CONFIGURATION :

A DESCRIPTION OF THE PROBLEM :
When using java web start jnlp file to launch an applet (applet-desc) the default downloading and verifying dialogs only appears if the java console is enabled. If the console is set to hide or do not start the dialogs are not shown. This is problematic when jars are being downloaded. This bug does not occur for a jws application (application-desc).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Clear java cache and hide the java console in the java control panel
2. Download jnlp file
3. Double click on jnlp file to launch web start

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
After double clicking the jnlp file and launching web start, the downloading and verifying dialog is displayed as the jars are downloaded. This happens only if the java console is enabled.
ACTUAL -
The initial java splash screen is briefly displayed but then disappears and then it appears nothing is happening while the jars are downloaded

REPRODUCIBILITY :
This bug can be reproduced always.
