FULL PRODUCT VERSION :
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+124)
Java HotSpot(TM) Client VM (build 9-ea+124, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
When I add a line
deployment.javaws.secure.properties=java.locale.providers
to the system-level or user-level deployment.properties file, the next Web Start launch after changing the property does not take into account the change


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
0. Ensure that no Java applications are running on the local computer
1. Deploy a small web start application that needs access to a secure property (see test code)
2. Sign the JAR file
3. Launch the app, it should fail with an exception. Close the app.
4. Add the line deployment.javaws.secure.properties=java.locale.properties to the system-level or user-level deployment.properties file as described in https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/properties.html
5. Launch the app a second time. Close the app.
6. Launch the app a third time. Close the app.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The application should fail the first time, but launch correctly the second and third times
ACTUAL -
The application only runs correctly the third time (that is, the second time after setting the deployment configuration correctly)

REPRODUCIBILITY :
This bug can be reproduced always.
