Smart client Servoy 7, 6 and 5.

After java-update 8U91 we’re getting “java.lang.SecurityException: class “com.jacob.com.JacobObject” does not match trust level of other classes in the same package”  
when using the COM-plugin.  
Spent many hours up to now.

We added in the servoyguy\_servoycom.jar.jnlp file : still error.  
We resigned all jar files : still error.

Help !

Lambert,

When you check the jar file(s) do you see only your signatures (2 files) or maybe others as well?

I see only my own signature.  
But I see on [Java SE 8u92 Advanced and Java SE 8u92 Support Release Notes](http://www.oracle.com/technetwork/java/javaseproducts/documentation/8u92-revision-builds-relnotes-2994940.html)  
for the bpr of 8u92 :

8145844  
(Confidential) deploy plugin JARSigningException when loading jar file from JRE\lib\applet

I tested and found out:

- no error when java cache disabled.
- no error when solution run from java cache (Servoy shortcut on desktop).
- no error when first time run after clearing java cache.

Maybe someone at Servoy can confirm this is a Java bug introduced in Java 8u91/92 ?  
Workaround?

</div>

so it is only a problem when running from cache?

Then that seeems to me like a real java bug, there is nothing servoy can do about that

You could start using the bootstrapper ([viewtopic.php?f=16&t=21190](https://www.servoy.com/forum/viewtopic.php?f=16&t=21190)) then these problems should not happen at all.

(but i guess you use native stuff and you have to do a bit more for that)

So Lambert,

In what scenario does it fail than?

I have now one customer that reports also an issue with java 8u91 on Mac, but in an other libarary:  
I somehow can’t reproduce it myself…

I have the same problem on a iMac.  
First I get a security warning (see picture). Both, the option ‘block’ and ‘dont block’ give the same result.

Hi Harjo,

It fails when started through shortcut “C:\ProgramData\Oracle\Java\javapath\javaws.exe [http://10.100.100.111:8080/servoy-client/main.jnlp](http://10.100.100.111:8080/servoy-client/main.jnlp)”  
and Java is using the cache (2nd (or 3rd) startup after clearing java cache).

I think (and hope?) it’s Java bug 8145844 (Confidential)

I can confirm, that in our case it ONLY goes wrong when you launch the smartclient through the console with: javaws javaws [https://xx.xxxxxxxx.xx/servoy-client/mySolution.jnlp](https://xx.xxxxxxxx.xx/servoy-client/mySolution.jnlp)

luckily, (almost) nobody uses this…

we just let the user download the jnlp from our website and than let the user start that. After that, java webstart creates a desktop icon, and users gonna use that.  
so not by using the console!

Strange, this is what is in the Servoy created desktop icon:  
“C:\Program Files (x86)\Java\jre1.8.0\_91\bin\javaws.exe” -localfile -J-Djnlp.application.href=[http://10.100.100.111:8080/servoy-client/main.jnlp](http://10.100.100.111:8080/servoy-client/main.jnlp) “C:\Users\lambert.ISPSOFTWARE\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\48\1ad52530-7d485725”  
This launches through the console as well…

</div>

in our case this in the shortcut:

```auto
"C:\Program Files\Java\jre1.8.0_73\bin\javaws.exe" -localfile "C:\Users\Harjo Kompagnie\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\13\5557600d-17db6e05"

```

I don’t see a jnlp or url entry

but I see in your case two different Java path’s ?

are you really using java 8u91 when starting via console?

</div>

1 “C:\ProgramData\Oracle\Java\*_javapath_\*\javaws.exe [http://10.100.100.111:8080/servoy-client/main.jnlp](http://10.100.100.111:8080/servoy-client/main.jnlp)”

Directory **javapath** is a so called symlink to the current Java installation. In my case 8u91.

2 “C:\Program Files (x86)\Java\jre1.8.0\_91\bin\javaws.exe” -localfile -J-Djnlp.application.href=[http://10.100.100.111:8080/servoy-client/main.jnlp](http://10.100.100.111:8080/servoy-client/main.jnlp) “C:\Users\lambert.ISPSOFTWARE\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\48\1ad52530-7d485725”

Both shortcuts point to the same javaws.exe

1. gives the error, 2) gives no error.  
Imho: the java cache plays some kind of role in this problem…

Hi Lambert,

I think I have found something

can you try to remove from the manifest file inside the jar: servoygoy\_servoycom.jar

the entries:

Name: .project  
SHA1-Digest: 0SjaO8qMCEP9qRlGSEgRPxG7EvE=

and

Name: .classpath  
SHA1-Digest: S7paNJWZfni+P5g1WWAXigp9uEc=

so every Name property, that does not have any resource

than sign the jar again, and try again?  
This will propably not fix the whole problem, because there are a lot more (3th party) plugins that have this problem. (not valid Name entries in the manifest)

i think those do have a resource  
that sounds like the jar is packed with eclipse project files (.classpath and .project)
