Hi,

When I used a custom filter and AJP13 filter, I met some problems(some AJP13
request/response was blocked) so I debugged mod_jk and grizzly-http-ajp
modules.
The problem was caused by reused buffer's byte order.

My custom filter used the buffer with little endian order(I set
Buffer#order(ByteOrder.LITTLE_ENDIAN)).
And the buffer and buffer's order also reused in AJP13 filter because the
buffer was cached(released) without resetting the byte order when it was
disposed. But AJP13 or most of filter assume that buffer's order is big
endian.

So, I think the buffer's order should be also cleared with default when it
is disposed and cached.

I attached the proposed patch based on 2.2.x.

Thanks!
