There is a regression noticing since JDK9-b28 that many existing applets out there failed to load or part of them failed to function. They worked find untill JDK 9-b27 and 8u20. The issue is platform/browser independent

Typical error occurred can be found at the end of this bug report.

*** Test Configurations:
- x86 Win 7/ FF, IE. x84 Ubuntu 12.04/ FF (should be on any platform, browser)
- jre9-b32, b28, b27
- Many applets in our applet compatibility suite (> 30 applets from different sites)

*** Steps to reproduce:
0) Install jre9-b32
1) Add "http://thejmaker.com to the ESL)
2) Use any browser to load the test applet
http://thejmaker.com/ThreeDimView/ThreeDimView.html
3) Accept to run unsigned app from the warning dialog

If the applet fails to load, the issue is reproducible. The issue does not happen if using jre9-b27 or 8u20 GA

* Other sample applets displaying the same issue:
