The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.
This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.
The existing implementation was exposed to very poor performance when matching
with multiple delimiters against a large buffer with many delimiters. In that
case all matchers are invoked many times (as many as the number of delimiters)
even though some of them found no match at all on the first pass.
The revised implementation uses a single index and advances all matchers
together, checking one byte a time, and not letting any one of them search to
the end of the entire buffer on a single pass.

Simplify and optimize the processing of the input stream.
The existing implementation was using bufferUntil and creating a List
for every line along with an EndFrameBuffer inserted for the
bufferUntil predicate. So the larger the input buffer and the more
lines it contained, the greater the overhead.
The new implementation avoids bufferUntil for all lines and
instead uses concatMapIterable to aggregate the lines from a buffer
into a single list. So the larger the input buffer and the more
lines it contains, the better the throughput. The only buffering
used then is for partial chunks and those are accumulated in a list.

Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.
This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.
Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.

We are passing custom values to the constructor of PooledByteBufAllocator in
tests in order to turn of caching. This is based on:
https://github.com/netty/netty/issues/5275#issuecomment-220547057
Netty 4.1.52 has significant changes in PooledByteBufAllocator:
https://github.com/netty/netty/pull/10267
After the changes, our current value for maxOrder=2, which results in
chunkSize=16K, causes an assert failure in PoolChunk where the runSize
exceeds the chunkSize.
Prior to this commit, if null values were supplied for the
RepeatableContainers or AnnotationFilter arguments to `from()` factory
methods in MergedAnnotations, certain operations would eventually
result in a NullPointerException. This is to be expected; however, the
NullPointerException is often swallowed and only logged at INFO level
with an exception message similar to the following.
> Failed to introspect annotations on org.example.MyClass: NullPointerException
In such cases, the INFO log message is not helpful in diagnosing the
problem. Furthermore, since the exception is swallowed, the desired
operation (e.g., MergedAnnotations.stream(...)) simply returns no
results.
This commit improves the user experience by eagerly asserting non-null
preconditions for required arguments in MergedAnnotations.from()
factory methods.

PR gh-25429 brought it to our attention that there was a bug in
AnnotationScanner when using a non-null class filter that filtered out
classes; however, it turns out that there is no production code that
utilizes the package-private class filtering support.
This commit therefore removes all class filtering support from
AnnotationScanner since that functionality is effectively unused.
Closes gh-25477
Prior to this commit, scanning for annotations resulted in an infinite
loop when using the INHERITED_ANNOTATIONS search strategy and a class
filter that filters out visited classes.
This commit avoids an infinite loop in AnnotationsScanner's
processClassInheritedAnnotations(...) method by skipping the current
level of the class hierarchy when the current source class has been
filtered out.

Prior to this commit, a Profiles instance created via Profiles.of() was
not considered equivalent to another Profiles instance created via
Profiles.of() with the exact same expressions. This makes it difficult
to mock invocations of Environment#acceptsProfiles(Profiles) -- for
example, when using a mocking library such as Mockito.
This commit makes Profiles instances created via Profiles.of()
"comparable" by implementing equals() and hashCode() in ParsedProfiles.
Note, however, that equivalence is only guaranteed if the exact same
profile expression strings are supplied to Profiles.of(). In other
words, Profiles.of("A & B", "C | D") is equivalent to
Profiles.of("A & B", "C | D") and Profiles.of("C | D", "A & B"), but
Profiles.of("X & Y") is not equivalent to Profiles.of("X&Y") or
Profiles.of("Y & X").

Prior to this commit, SocketUtils used System.currentTimeMillis() for
the seed for the java.util.Random instance used internally. The use of
the milliseconds value returned by currentTimeMillis() can lead to
collisions for randomly selected free ports for tests executing in
parallel on the same computer.
This commit therefore switches to System.nanoTime() for the Random seed
used in SocketUtils in an attempt to avoid such collisions for tests
executing in parallel in different JVMs on the same computer.

Prior to this commit, a change to Javadoc in any class in spring-core
would result in ALL tests in the entire test suite being re-run via the
Gradle build.
Thanks to a tip from @melix, this commit aims to ensure that the
spring-core JAR is "reproducible".
