Defect #1016
Java update 8u91
0%
Description
After updating to JVM 8u91 we get :
"java.lang.SecurityException: class "com.jacob.com.JacobObject" does not match trust level of other classes in the same package"
when using the plugin. We sign all jars with our own signing certificate (for many years).

Can you try using the visual signer tool at: https://www.servoyforge.net/projects/code-signer and verify the servoyguy_servoycom.jar is signed with the same cert as /servoyguy_servoycom/jacob.jar?

Yep, I did use the 1.3.3 version of the codesigner8.jar to sign all our jar files, but error stays.
It's getting weird :
- no error when java cache disabled.
- no error when solution run from java cache (Servoy shortcut on desktop). jnlp file attached
- no error when first time run after clearing java cache.
- error when run with filled java cache through "C:\\\\ProgramData\\\\Oracle\\\\Java\\\\javapath\\\\javaws.exe http://10.100.100.111:8080/servoy-client/main.jnlp"
Javawebstart bug introduced ?

See servoy forum 21286. jacob.jar manifest issue.
Maybe update the jacob.jar ?
