FULL PRODUCT VERSION :
Java Web Start 11.72.2.15
JRE-Version verwenden 1.8.0_72-b15 Java HotSpot(TM) 64-Bit Server VM

ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
Starting the application from JNLP file (or browser), an JARSigningException is thrown:

com.sun.deploy.net.JARSigningException: Signatur konnte nicht verifiziert werden in Ressource: https://trial.amparex.net:443/amparex/lib/generic/generic_client.jar
	at com.sun.deploy.security.TrustDecider.ensureAllJarEntriesSigned(Unknown Source)
	at com.sun.deploy.security.TrustDecider.getValidationState(Unknown Source)

	at com.sun.deploy.security.TrustDecider.isAllPermissionGranted(Unknown Source)
	at com.sun.deploy.security.DeployURLClassLoader.getResourcePermission(Unknown Source)
......


Using JRE18_71 (with Java Web Start 11.71.2.15) the signed JARs could be verified with success and the application is running.
