We have installed the Java Version 8 latest update 331 and post that we are unable to open the IM Console, although im_jboss service is running fine , while accessing the IM Console URL it is showing a white screen / "This page can't be displayed"
Release : 14.3 CPx / 14.4 CPx
Component : IdentityMinder(Identity Manager)
JBoss / Wildfly core integration with JDK 1.8.0_331
As per https://access.redhat.com/solutions/6953431 this is a known issue which Red Hat is currently investigating.
While a fix is planned for an official Red Hat release.
As a workaround, you may downgrade the JDK or add the following system property:
-Djdk.io.File.enableADS=true
The same error would be visible when integrating an OOTB JBoss / Wildfly with JDK 1.8.0_331 and trying to access the application server management console post add-user procedure.
