Historically, we have used `<introduction year>-<modification year>` as
the pattern for copyright headers.
For example: `Copyright 2002-2025 the original author or authors.`
However, we have been encouraged to use `present` as the modification
year.
In light of that, this commit updates the following to enforce the new
pattern.
- The patterns in our SpringHeaderCheck Checkstyle rules
- The `Copyright 2002-${year}` template in org.eclipse.jdt.ui.prefs
- The update_copyright_headers.sh script
See gh-35070

Based on RetryTemplate with ExponentialBackOff.
Includes optional jitter support in ExponentialBackOff.
Supports reactive methods through Reactor's RetryBackoffSpec.

Prior to this commit, the `DefaultServerWebExchange` would attempt to
decode request bodies as form-data or multipart of the request
content-type was compatible with the expected media types.
If requests are sent with an invalid wildcard content-type such as "*/*"
or "multipart/*", we should not attempt to decode here.
Fixes gh-34660
Prior to this commit, we had three concrete RetryPolicy implementations.
- MaxRetryAttemptsPolicy
- MaxDurationAttemptsPolicy
- PredicateRetryPolicy
However, there was no way to combine the behavior of those policies.
Furthermore, the PredicateRetryPolicy was practically useless as a
standalone policy, since it did not have a way to end an infinite loop
for a Retryable that continually throws an exception which matches the
predicate.
This commit therefore replaces the current built-in RetryPolicy
implementations with a fluent Builder API and dedicated factory methods
for common use cases.
In addition, this commit also introduces built-in support for
specifying include/exclude lists.
Examples:
new MaxRetryAttemptsPolicy(5) -->
RetryPolicy.withMaxAttempts(5)
new MaxDurationAttemptsPolicy(Duration.ofSeconds(5)) -->
RetryPolicy.withMaxDuration(Duration.ofSeconds(5))
new PredicateRetryPolicy(IOException.class::isInstance) -->
RetryPolicy.builder()
.maxAttempts(3)
.predicate(IOException.class::isInstance)
.build();
The following example demonstrates all supported features of the builder.
RetryPolicy.builder()
.maxAttempts(5)
.maxDuration(Duration.ofMillis(100))
.includes(IOException.class)
.excludes(FileNotFoundException.class)
.predicate(t -> t.getMessage().contains("Unexpected failure"))
.build();
Closes gh-35058
Exposes last exception as cause in RetryException.
Applies first back-off after the initial exception.
Breaks out of retry loop on BackOffExecution.STOP.
Expects null result in Retryable and RetryListener.
Closes gh-35057
Prior to this commit, the `ResourceHttpRequestHandler` would detect
invalid range requests and reply with a 416 response status and the
relevant range header. Because this was triggering an error dispatch,
the error handling would collect error metadata and produce an error
response with the original content-type.
This would most likely fail because the content-type is most likely a
file-related media type which cannot be used for error responses.
This commit resets the response content type in these cases and let the
error handling pick the most sensible media type for the error response.
Fixes gh- 34490
This commit configures a new CheckStyle rule that fails for empty
"catch" blocks, unless the exception is named "ignored" or "expected".
This also fixes the remaining instances missed by the previous commit.
Closes gh-35047
The Spring codebase sometimes ignores exceptions in catch blocks on
purpose. This is often called out by an inline comment.
We should make this more obvious by renaming the exception argument in
the catch block to declare whether the exception is "ignored" or
"expected".

Prior to this commit, the WebFlux server support would try reading
form-data from the request by:
* first, checking that request content-type is compatible with a
form-data content-type
* then by selecting a message reader that is compatible with the given
request content-type
This approach is flawed because if the content-type provided by the
request is too broad, another message reader could be selected that's
not meant to be used for reading form-data. Typically, a JSON message
reader could be selected and would fail when reading the request.
This problem was previously hidden because message readers would not
support `MultiValueMap` as a target type. Now that some readers support
this type, this can lead to deserialization errors.
This commit now ensures that in all cases, we attempt to read form-data
with a message reader that supports the
"application/x-www-form-urlencoded" media type.

While we choose our GitHub action to use Bellsoft Liberica, we should
relax that vendor requirement and ensure that contributors can build the
project with any Java 24 distribution.
Closes gh-35043
Use String.replace instead of replaceAll in MetadataEncoder; since Java 9, String.replace
no longer uses a regex, while replaceAll does. The use case here of replacing a single
character does not require a regex.

Prior to this commit, the "filename" parameter value for the
"Content-Disposition" header would contain non-printable characters,
causing parsing issues for HTTP clients.
This commit ensures that all non-printable characters are encoded.
Fixes gh-35034
Due to lacking support in NullAway for the current arrangement, we are
(perhaps temporarily) changing the signature of the execute() method in
RetryOperations (and thus also in RetryTemplate)...
from: <R extends @Nullable Object> R execute(Retryable<R> retryable);
to: <R> @Nullable R execute(Retryable<? extends @Nullable R> retryable);
Once https://github.com/uber/NullAway/issues/1075 has been resolved, we
will consider switching back to the original signature.
