In order to prevent leaks of large amounts of non-heap
memory (and potential other efficiency and performance side
effects), this commit updates ResourceUtils#useCachesIfNecessary
to leave the caching flag to its JVM default value for instances
of JarURLConnection.
The previous behavior was originally introduced via gh-9316 and
gh-13755 to avoid I/O failure during webapp hot reloading in
Servlet containers. This is not a popular deployment mode anymore
and we have not been able to reproduce the original issue with
a Java 17 JVM and Tomcat 10.
Closes gh-30955
Legacy EJB attributes are ignored since 6.0 due to being bound to a plain JndiObjectFactoryBean - but can still be declared now, e.g. when validating against the common versions of spring-jee.xsd out there.
Closes gh-31627
The description is for WebFlux, but the link points to WebFlux unit
testing support.
This commit changes the link to point the the WebFlux chapter.
Closes gh-31632
Adding generated code in the default package is not supported as we
intend to import it, most probably from another package, and that is
not supported. While this situation is hard to replicate with Java,
Kotlin is unfortunately more lenient and users can end up in that
situation if they forget to add a package statement.
This commit checks for the presence of a valid package, and throws
a dedicated exception if necessary.
Closes gh-31628
Prior to this commit, the getResource() methods in PathResourceResolver
implementations allowed an exception thrown from Resource#getURL() to
propagate instead of logging a warning about the missing resource as
intended.
This commit modifies the getResource() methods in PathResourceResolver
implementations so that the log messages include the output of the
toString() implementations of the underlying resources instead of their
getURL() implementations, which may throw an exception.
Furthermore, logging the toString() output of resources aligns with the
existing output for "allowed locations" in the same log message.
Note that the toString() implementations could potentially also throw
exceptions, but that is considered less likely.
Closes gh-31623
This commit makes sure that the per-operation execution context for
caching and event listening does not recreate the default internal
delegates, but rather get initialized with a shared state.
This reduces the number of instances created per operation execution,
reducing the GC pressure as a result. This also makes sure that any
cache, such as the one in StandardTypeLocator, is reused.
Closes gh-31617
