I had to fix several compiler errors due to deprecation of auto application of `()`. A related
Xlint config (`-Xlint:nullary-override`) is no longer valid in 2.13, so we now only enable it
for 2.12. The compiler flagged two new inliner warnings that required suppression and
the semantics of `&` in `@nowarn` annotations changed, requiring a small change in
one of the warning suppressions.
I also removed the deprecation of a number of methods in `KafkaZkClient` as
they should not have been deprecated in the first place since `KafkaZkClient` is an
internal class and we still use these methods in the Controller and so on. This
became visible because the Scala compiler now respects Java's `@Deprecated`
annotation.
Finally, I included a few minor clean-ups (eg using `toBuffer` instead `toList`) when fixing
the compilation warnings.
Noteworthy bug fixes in Scala 2.13.3:
* Fix 2.13-only bug in Java collection converters that caused some operations to perform an extra pass
* Fix 2.13.2 performance regression in Vector: restore special cases for small operands in appendedAll and prependedAll
* Increase laziness of #:: for LazyList
* Fixes related to annotation parsing of @Deprecated from Java sources in mixed compilation

Scala 2.13.2 introduces support for suppressing warnings,
which makes it possible to enable fatal warnings. This is
useful enough from a development perspective to justify
this change.
In addition, Scala 2.13.2 also has a Vector implementation
with significant performance improvements and encoding
of String matches to switches.
Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>
Highlights:
* Performance improvements in the ollections
library: algorithmic improvements and
changes to avoid unnecessary allocations.
* Performance improvements in the compiler.
* ASM was upgraded to 7.3.1, allowing the
optimizer to run on JDK 13+.

Some shell scripts don't have corresponding batch files in bin\windows.
For improving Windows platform support, This PR adds the following batch files:
- bin\windows\kafka-delete-records.bat
- bin\windows\kafka-log-dirs.bat
Reviewers: Jason Gustafson <jason@confluent.io>
Removed quotes from LogDir variable generation as there are additional quotes in Line 127.
This caused problems when those batch files are invoked from a path that contains space characters.
Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.

It seems a tipo was made on a avariable for the log dir with commit 81e789ae3dc6ea8369db181c5aef440491d74f19. Then Windows tries to access by default the /log directory which of cause not exists.
klesta490 Is it ok so? Or was the tilde ~ intentional?
To test:
On Windows with the a fresh downloaded Kafka, adapt the properties:
* dataDir in config/zookeeper.properties with what you want, windows-compatible
* log.dirs in config/server.properties with what you want, windows-compatible
and executes:
bin\windows\zookeeper-server-start.bat config\zookeeper.properties

Closes#5837 from florianhof/feature/fix_windows_log_param
- Removed Scala consumers (`SimpleConsumer` and `ZooKeeperConsumerConnector`)
and their tests.
- Removed Scala request/response/message classes.
- Removed any mention of new consumer or new producer in the code
with the exception of MirrorMaker where the new.consumer option was
never deprecated so we have to keep it for now. The non-code
documentation has not been updated either, that will be done
separately.
- Removed a number of tools that only made sense in the context
of the Scala consumers (see upgrade notes).
- Updated some tools that worked with both Scala and Java consumers
so that they only support the latter (see upgrade notes).
- Removed `BaseConsumer` and related classes apart from `BaseRecord`
which is used in `MirrorMakerMessageHandler`. The latter is a pluggable
interface so effectively public API.
- Removed `ZkUtils` methods that were only used by the old consumers.
- Removed `ZkUtils.registerBroker` and `ZKCheckedEphemeral` since
the broker now uses the methods in `KafkaZkClient` and no-one else
should be using that method.
- Updated system tests so that they don't use the Scala consumers except
for multi-version tests.
- Updated LogDirFailureTest so that the consumer offsets topic would
continue to be available after all the failures. This was necessary for it
to work with the Java consumer.
- Some multi-version system tests had not been updated to include
recently released Kafka versions, fixed it.
- Updated findBugs and checkstyle configs not to refer to deleted
classes and packages.

This is important because Bits.reserveMemory calls System.gc() hoping to free native
memory in order to avoid throwing an OutOfMemoryException. This call is currently
a no-op due to -XX:+DisableExplicitGC.
It's worth mentioning that -XX:MaxDirectMemorySize can be used to increase the
amount of native memory available for allocation of direct byte buffers.
