Hello again, I see this bug is fixed in 5.4 https://issues.apache.org/jira/browse/TAP5-2430 Can you backport it to 5.3.8 ? We would really like an Index page and be able to access our app with only the root url without seeing an error every time we clear our cache. The Index page concerned is, for purposes of testing the bug, empty except for "foobar" in the body. The error happens when you access the index page, using only the root url or even the direct url /index . The error also happens when you use the /start url, which redirects to the index page.
So something is happening the first time you access the index page which generates this error. The error's cause is that the content type of the generated page is null. But returning false instead of generating an exception doesn't solve the underlying problem, does it?
