How to resolve “ Found unsigned entry in resource:”

If, in your .jnlp file you are referencing some signed jars, sometimes the verification fails miserably with the following stacktrace: entry in resource: 
	at com.sun.javaws.LaunchDownload.checkSignedResourcesHelper(UnknownSource)
	at com.sun.javaws.LaunchDownload.checkSignedResources(UnknownSource)
	at com.sun.javaws.Launcher.prepareResources(UnknownSource)
	at com.sun.javaws.Launcher.prepareAllResources(UnknownSource)
	at com.sun.javaws.Launcher.prepareToLaunch(UnknownSource)
	at com.sun.javaws.Launcher.prepareToLaunch(UnknownSource)
	at com.sun.javaws.Launcher.launch(UnknownSource)
	at com.sun.javaws.Main.launchApp(UnknownSource)
	at com.sun.javaws.Main.continueInSecureThread(UnknownSource)
	at com.sun.javaws.Main$

If you are 100% sure that your jars are correctly signed, check if your JRE setup have “Keep temporary files on my computer” option disabled.

So if you are on Windows/MacOS: Control Panel -> Java and then:


Please make sure "“Keep temporary files on my computer" are UNTICKED.
