There were a couple of important issues fixed in Gradle 3.2.1:
* [GRADLE-3582] - Gradle wrapper fails to escape arguments with nested quotes
* [GRADLE-3583] - Newlines in JAVA_OPTS breaks application plugin shell script in Gradle 3.2
And a lot of important issues fixed in Scala 2.12.1:

The NamedCache wasn't correctly dealing with its re-entrant nature. This would result in the LRU becoming corrupted, and the above exception occurring during eviction. For example:
Cache A: dirty key 1
eviction runs on Cache A
Node for key 1 gets marked as clean
Entry for key 1 gets flushed downstream
Downstream there is a processor that also refers to the table fronted by Cache A
Downstream processor puts key 2 into Cache A
This triggers an eviction of key 1 again ( it is still the oldest node as hasn't been removed from the LRU)
As the Node for key 1 is clean flush doesn't run and it is immediately removed from the cache.
So now we have dirtyKey set with key =1, but the value doesn't exist in the cache.
Downstream processor tries to put key = 1 into the cache, it fails as key =1 is in the dirtyKeySet.

NPE was caused by `log.logSegments.toArray` resulting in array containing `null` values. The exact reason still remains somewhat a mystery to me, but it seems that the culprit is `JavaConverters` in combination with concurrent data structure access.
Here's a simple code example to prove that:
```scala
import java.util.concurrent.ConcurrentSkipListMap
// Same as `JavaConversions`, but allows explicit conversions via `asScala`/`asJava` methods.
import scala.collection.JavaConverters._
case object Value
val m = new ConcurrentSkipListMap[Int, Value.type]
new Thread { override def run() = { while (true) m.put(9000, Value) } }.start()
new Thread { override def run() = { while (true) m.remove(9000) } }.start()
new Thread { override def run() = { while (true) { println(m.values.asScala.toArray.headOption) } } }.start()
```
Running the example will occasionally print `Some(null)` indicating that there's something shady going on during `toArray` conversion.
`null`s magically disappear by making the following change:
```diff
- println(m.values.asScala.toArray.headOption)
+ println(m.values.asScala.toSeq.headOption)
```

Also:
* Make all implementations of `Time` thread-safe as they are accessed from multiple threads in some cases.
* Change default implementation of `MockTime` to use two separate variables for `nanoTime` and `currentTimeMillis` as they have different `origins`.

This reverts commit e035fc0395 for the
following reasons:
1. License files are missing causing local builds to fail during the
rat task (rat is not being run in Jenkins for some reason, filed
KAFKA-4459 for that)
2. It renames a number of system test files when there's a better
way to achieve the goal of running a subset of system tests to stay
under the Travis limit.
3. It adds the gradle wrapper binary even though this was removed
intentionally a while back.
A new PR will be submitted for KAFKA-4345 without the undesired
changes.
