Modify the HTTP/2 connector not to sent small updates for stream flow
control windows to the user agent as, depending on how the user agent is
written, this may trigger small writes from the user agent that in turn
trigger the overhead protection. Small updates for stream flow control
windows are now combined with subsequent flow control window updates for
that stream to ensure that all stream flow control window updates sent
from Tomcat are larger than overheadWindowUpdateThreshold.
(markt)
Add additional debug logging to track the current state of the HTTP/2
overhead count that Tomcat uses to detect and close potentially
malicious connections. (markt)
Many HTTP/2 requests from browsers will trigger one overhead frame and
one non-overhead frame. Change the overhead calculation so that a
non-overhead frame reduces the current overhead count by 2 rather than
1. This means that, over time, the overhead count for a well-behaved
connection will trend downwards. (markt)
Change the initial HTTP/2 overhead count from -10 to
-10 * overheadCountFactor. This means that, regardless of
the value chosen for overheadCountFactor, when a connection
opens 10 overhead frames in a row will be required to trigger the
overhead protection. (markt)
Increase the default overheadCountFactor from
1 to 10 and change the reduction in overhead
count for a non-overhead frame from -2 to -20.
This allows for a larger range (0-20) to be used for
overheadCountFactor providing for finer-grained control.

Correct parsing of HTTP headers consisting of a list of tokens so that a
header with an empty token is treated consistently regardless of whether
the empty token is at the start, middle or end of the list of tokens.
(markt)
Remove support for the identity transfer encoding. The
inclusion of this encoding in RFC 2616 was an error that was corrected
in 2001. Requests using this transfer encoding will now receive a 501
response. (markt)
Process transfer encoding headers from both HTTP 1.0 and HTTP 1.1
clients. (markt)
Ensure that if the transfer encoding header contains the
chunked, that the chunked encoding is the
final encoding listed. (markt)
Jasper
Incremented the supported Jakarta Expression Language version to 5.0 to
align with the current development branch of the Jakarta Expression
Language specification. (markt)
Review code used to generate Java source from JSPs and tags and remove
code found to be unnecessary. (markt)
Refactor use of internal ChildInfo class to use compile
time type checking rather than run time type checking. (markt)
65124: Partial fix. When generating Java source code to call
a tag handler, only define the local variable JspWriter out
when it is going to be used. (markt)
Add generics to the EL 5.0 API to align with the current EL 5.0
development branch. (markt)
Update the web-fragment.xml included in
jasper.jar and jasper-el.jar to use the
Servlet 5.0 schema. (markt)
Update JspC to generate web.xml and
web-fragment.xml files using Servlet 5.0 schemas. (markt)
Remove the deprecated method
MethodExpression.isParmetersProvided() from the EL API to
align with the current EL 5.0 development branch. (markt)
65358: Improve expression language method matching for
methods with varargs. Where multiple methods may match the provided
parameters, the method that requires the fewest varargs is preferred.
(markt)
65332: Add a commented out section in
catalina.policy that provides the necessary permissions to
compile JSPs with javac when running on Java 9 onwards with a security
manager. It is commented out as it will cause errors if used with
earlier Java versions. (markt)
WebSocket
65317: When using permessage-deflate, the
WebSocket connection was incorrectly closed if the uncompressed payload
size was an exact multiple of 8192. Based on a patch provided by Saksham
Verma. (markt)
Update the web-fragment.xml included in
tomcat-websocket.jar to use the Servlet 5.0 schema. (markt)
65342: Correct a regression introduced with the fix for
65262 that meant Tomcat's WebSocket implementation would only
work with Tomcat's implementation of the Jakarta WebSocket API. (markt)

Improve the description of the maxConnections and
acceptCount attributes in the Connector section of the
documentation web application. (markt)
Other
Improvements to French translations. (remm)
Improvements to Korean translations. (woonsan)

change to create OSGi Require-Capability sections in
manifests for Jakarta API JARs manually rather than with bnd annotations
did not add the necessary manual entries to the embedded JARs. (markt)
Update the packaged version of the Tomcat Native Library to 1.2.30. Also
update the minimum recommended version to 1.2.30. (markt)
