VfsResource.getFile() broken on Wildfly 14.0.1 [SPR-17563]

[spring-issuemaster]

Kristiaan Lenaerts opened SPR-17563 and commented

Deployment of the Apereo CAS application https://apereo.github.io/cas/5.3.x/ on wildfly 14.0.1 fails with following stacktrace:
14:58:14,539 ERROR [org.springframework.boot.SpringApplication] (ServerService Thread Pool -- 95) Application startup failed: java.lang.IllegalArgumentException: object is not an instance of declaring class

This also affect Jboss EAP 7.1.5 and 6.4.21

This is caused by a change in the VFS layer: jbossas/jboss-vfs#28
The proposed fix jbossas/jboss-vfs#30 does not reintroduce the old behaviour, but adds a new accessor that can be used to get the undelying file.

The workaround from Drools can be found here: kiegroup/drools@2a36f67 - this should work on either version of wildfly/jboss

As far as I can tell, the fix needs to go into https://github.com/apereo/cas/blob/master/core/cas-server-core-util-api/src/main/java/org/apereo/cas/util/CasVersion.java since the VfsResource instance is being created from a getContent() call there. At the Spring Framework level, we're just expecting VfsResource to be created with a VirtualFile instance, and for all internal code paths of ours, this is still reliably the case. And for an externally created VfsResource instance, it is the calling code's responsibility to pass in a matching resource handle.
