New Java Update Causes WebNow Crash

posted Jul 28, 2017, 7:38 AM by Stephen Blaylock
The new or latest Java update is incompatible with the WebNow portal.  Java 8.141 causes a WebNow security issue and can not verify a resource.  Short answer, WebNow can not connect to the ImageNow server. 

Resolution
 
There is an unintentional breaking change with the jar signing and verification that was introduced by Oracle in the Java 8 patch 141 released July 18, 2017.

This issue effects all versions of WebNow. This issue may also impact the Java based Forms Server client on pre 7.1.2 versions of Perceptive Content before the HTML based Forms Server client was introduced.

The issue is resolved by updating the client JRE to Java 8 patch 144 on workstations where WebNow is being accessed.

Java™ SE Development Kit 8, Update 144 (JDK 8u144)
