Hi,

We are working on developing a module that uses JXBrowser library ([https://www.teamdev.com/jxbrowser](https://www.teamdev.com/jxbrowser)) for providing one of the functionalities in Vision Client Component.

I have an evaluation license and building the module with 7.9.3 SDK.  
The module is built successfully however, when I try to launch the designer, we get following error:

java.lang.SecurityException: SHA-256 digest error for com/teamdev/jxbrowser/chromium/swing/BrowserView.class

at com.inductiveautomation.vision.api.designer.beans.CommonBeanInfo.initProperties(CommonBeanInfo.java:245)

This seems similar to [Error uploading custom module](http://forum.inductiveautomation.com/t/error-uploading-custom-module/12543)  
However as suggested this does not seem to be an issues with pack200 because the module file contains the required pack.gz entries as below:  
jxbrowser-6.0.jar.pack.gzjxbrowser-win-6.0.jar.pack.gz

Java version we are using is : jdk1.8.0\_161  
Ignition SDK : 7.9.3  
Ignition Version : 7.9.4, 7.9.5  
JXBrowser : 6.0

Appreciate help in resolving the issue above.

This issue is resolved when we upgraded to latest 6.18 version of JXBrowser.
