Someone else already stumbled upon this but it's not yet confirmed
what's causing it. I believe Howard posted a workaround in the issue
comments. https://issues.apache.org/jira/browse/TAP5-469

Another day, another couple of stumbling blocks for our applications migration
to T5.1 - I can't believe this has taken a solid week of effort so far. I'm
starting to wonder if we jumped the gun on moving to T5.1 so soon? I do seem to
be having more problems than most people on the list, so maybe it's just me /
our app or something.
Anyway, the first issue is with our checkbox components that do an Ajax call when checked
or unchecked. They work fine if Gzip compression is switched off, but if it's enabled the
Ajax.Request hits the onException block with this error message "TypeError: response
is null". The server event handler is being called correctly and returning the
correct JSONObject, but the responseText is empty and responseXML, responseJSON, and
headerJSON are all null even though the status code is 200. My guess that the JSONObject
is being compressed and it shouldn't be. Should I raise a JIRA for this, or am I mistaken
here?
I also have a page that works fine with T5.0.18 but breaks in T5.1.0.2 and I have no idea why -
curiously, if I have gzip compression I don't see the stacktrace in the browser, but I get
"Content Encoding Error", "The page you are trying to view cannot be shown because
it uses an invalid or unsupported form of compression." From Firefox.
Here is the stack trace, in case anyone can make any sense of it:
