CompressionAnalyzerImpl exception
I just started using gzip etc and I'm not getting the following exception.
Does anybody know what it means or how to fix it?

While the root cause for the contentType being null is somewhere else,
CompressionAnalyzerImpl should probably just return false on null
contentType rather than throw an exception.

That's a bug and I'll fix it. JIRA please? :)

Howard, you were correct. the MIME type was null. CompressionAnalyzerImpl
was failing on line 32 do to contentType being null. As you stated, this
NPE is a failure and should probably be checked and thrown with a proper
message. I ended up having to override the service in order to resolve the
issue.

Re: CompressionAnalyzerImpl exception
Posted by George Christman <gc...@cardaddy.com>.
So tonight I was playing around on the site and I noticed I somehow was
able to triggered this exception. If it didn't appear in the logs, it would
have gone completely unnoticed. Now I will say I logged in using facebook
which uses oauth and at some point during the login process, this exception
was triggered. Here's the exception in it's entirety.

Re: CompressionAnalyzerImpl exception
Posted by Howard Lewis Ship <hl...@gmail.com>.
Well, right off the bat, any NPE like this (with no additional message to
explain it) is a failure.
Was there anything special about the page being rendered? It seems like
the MIME type of the page is null, that's what might cause this NPE.
