ScriptTemplateView should check template resource [SPR-14729]

[spring-projects-issues]

Brian Clozel opened SPR-14729 and commented

The ScriptTemplateView class does not override the checkResource method. This means that, when configuring multiple template resolvers within an application, the ScriptTemplateViewResolver won't properly check if a template is available before trying to render it, thus throwing an exception.
The next view resolvers in the chain are then never called.

Brian Clozel, I've revised this check to avoid exception swallowing (and full template loading) and rather delegate to getResource directly, making the latter return null in case of no resource found. I hope that's in alignment with your original intention here.
