'Template not found' sticky even after creation of .gsp file till application restart.

[mkrasuski]

Steps to Reproduce

in development mode

1. call <g:render template="newTemplate"></g:render> somewhere on existing page without creating _newTemplate.gsp
2. run code - 'Template not found' will arise
3. create relevant _newTemplate.gsp
4. run code again - 'Template not found' is sticky

Expected Behaviour

After creation of template file template should be compiled and rendered.

Actual Behaviour

Error of non-existing template is sticky till restart of application. That's VERY annoying
