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.
See gh-34716
This commit constitutes a first pass over the new core retry support.
- Fix code and Javadoc formatting
- Polish/fix Javadoc
- Fix default FixedBackOff configuration in RetryTemplate
- Consistent logging in RetryTemplate
- Fix listener handling in CompositeRetryListener, allowing addListener()
to work
- Polish tests
- Ensure RetryTemplateTests do not take over 30 seconds to execute
See gh-34716
This commit introduces a minimal core retry feature. It is inspired
by Spring Retry, but redesigned and trimmed to the bare minimum to
cover most cases.
Closes gh-34716
Add optimized DataBufferInputStream overrides for readNBytes, skip, and transferTo; all of them
allocate byte buffers which we can either avoid (in the case of skip) or size more precisely since
the number of remaining bytes is known.

NonClosingInputStream extends FilterInputStream, which does not forward some
newer InputStream methods such as transferTo and readAllBytes. Specific InputStream
implementations may have more optimized methods (e.g., FileInputStream).

Spring Framework 6.2 introduced support for an escape character for
property placeholders (by default '\'). However, as of Spring Framework
6.2.6, there was no way to either escape the escape character or disable
escape character support.
For example, given a `username` property configured with the value of
`Jane.Smith` and a `DOMAIN\${username}` configuration string, property
placeholder replacement used to result in `DOMAIN\Jane.Smith` prior to
6.2 but now results in `DOMAIN${username}`. Similarly, an attempt to
escape the escape character via `DOMAIN\\${username}` results in
`DOMAIN\${username}`.
In theory, one should be able to disable use of an escape character
altogether, and that is currently possible by invoking
setEscapeCharacter(null) on AbstractPropertyResolver and
PlaceholderConfigurerSupport (the superclass of
PropertySourcesPlaceholderConfigurer).
However, in reality, there are two hurdles.
- As of 6.2.6, an invocation of setEscapeCharacter(null) on a
PropertySourcesPlaceholderConfigurer applied to its internal
top-level PropertySourcesPropertyResolver but not to any nested
PropertySourcesPropertyResolver, which means that the `null` escape
character could not be effectively applied.
- Users may not have an easy way to explicitly set the escape character
to `null` for a PropertyResolver or
PropertySourcesPlaceholderConfigurer. For example, Spring Boot
auto-configures a PropertySourcesPlaceholderConfigurer with the
default escape character enabled.
This first issue above has recently been addressed by gh-34861.
This commit therefore addresses the second issue as follows.
- To allow developers to easily revert to the pre-6.2 behavior without
changes to code or configuration strings, this commit introduces a
`spring.placeholder.escapeCharacter.default` property for use with
SpringProperties which globally sets the default escape character that
is automatically configured in AbstractPropertyResolver and
PlaceholderConfigurerSupport.
- Setting the property to an empty string sets the default escape
character to `null`, effectively disabling the default support for
escape characters.
spring.placeholder.escapeCharacter.default =
- Setting the property to any other character sets the default escape
character to that specific character.
spring.placeholder.escapeCharacter.default = ~
- Setting the property to a string containing more than one character
results in an exception.
- Developers are still able to configure an explicit escape character
in AbstractPropertyResolver and PlaceholderConfigurerSupport if they
choose to do so.
- Third-party components that wish to rely on the same feature can
invoke AbstractPropertyResolver.getDefaultEscapeCharacter() to obtain
the globally configured default escape character.

Prior to this commit, the new `ClassFileAnnotationMetadata` would fail
when reading `Class<T>` annotation attributes when values are primitive
types.
This commit uses `java.lang.constant.ClassDesc` to better parse type
descriptors from the bytecode.
Fixes gh-24882
Update `ClassFileClassMetadata` so that member classes only include
immediate children. This aligns with the other `ClassMetadata`
implementations.
Closes gh-34869
Update `ClassFileClassMetadata` to align the behavior of
`getSuperClassName()` with other readers in that it returns
`null` for `package-info` classes.
