This commit upgrades the baseline to Tomcat 11.0 and adapts to the
following behavior changes in Tomcat:
* the MimeHeaders#clear method has been removed
* expired cookies do not set "Max-Age=0" anymore
* responses to HEAD requests do not write the "Content-Length" header
anymore.
Closes gh-33916
This commit updates the Spring Framework baseline for the Servlet, JSP
and WebSocket APIs.
This also removes the previously deprecated APIs in JSP `PageContext`
and guards against the deprecation of the `PushBuilder` API.
See gh-33918
This ensures that the reactive handling of the request is dispatched
from the Undertow IO thread, marking the exchange as async rather than
ending it once the Undertow `handleRequest` method returns.
Closes gh-33885
Since Joda-Time support was removed in Spring Framework 6.0, this commit
removes obsolete mentions of Joda-Time in the reference guide and Javadoc.
See gh-27426
Closes gh-33881
Prior to this commit, a client sending a request to
"https://example.org" would record the wrong URI tag as
"/https://example.org".
This commit ensures that the scheme+host part is matched correctly in
the default client observation conventions.
See gh-33867
The `HttpHeaders#headerSet` method is intended as a drop-in replacement
for `entrySet` that guarantees a single casing for all header names
reported during the iteration, as the cost of some overhead but with
support for iterator removal and entry value-setting.
The `formatHeaders` static method is also altered to do a similar
deduplication of casing variants, but now additionally mentions
"with native header names [native name set]" if the native name set
contains casing variants.
Closes gh-33823
Prior to this commit, the `HttpHeaders.writeableHttpHeaders` would only
consider headers read-only instances that were wrapped once by
`HttpHeaders.readOnlyHttpHeaders`. This does not work when other
`HttpHeaders` wrappers are involved in the chain.
This commit ensures that `writeableHttpHeaders` unwraps all headers
instances down to the actual multivalue map and create a new headers
instance out of it.
Fixes gh-33789
This commit removes all references to the Resin Servlet container, as it
is not supported as of Spring Framework 6.0 because we require a
JakartaEE baseline.
Closes gh-33772
