Fix intermittent failures of WatchTest

[rohanKanojia]

I've noticed WatchTest failing intermittently on CI sometimes, for example here. We should fix these intermittent failures whenever we get some time:

[INFO] 
[INFO] Results:
[INFO] 
Error:  Failures: 
Error:    WatchTest.testHttpErrorReconnect:192 expected: <true> but was: <false>
[INFO] 
Error:  Tests run: 919, Failures: 1, Errors: 0, Skipped: 4

[manusa]

kubernetes-client/kubernetes-tests/src/test/java/io/fabric8/kubernetes/client/mock/WatchTest.java

Line 192 in d1740ff

assertTrue(closeLatch.await(3, TimeUnit.MINUTES));

[manusa]

I'm not able to force a local failure:

• Ran individual test >100 times continuously (from IDE). ✔️
• Ran class suite >225 times continuously (from IDE). ✔️

OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9 (build 11.0.11+9)

Maybe we can run this test only on linux/unix platforms?

  @Test
  @EnabledOnOs({OS.LINUX, OS.MAC})
  void testHttpErrorReconnect() throws InterruptedException {

[manusa]

I don't like this, but we'll probably need to do it.

We are using 5.12.4 and facing the issue "onClose is not getting invoked". I suspect that this issue is related to it. But I am not able to relate it.

Could someone explain me that why onClose will not be invoked due to this ticket?

Also, help me to understand that how to solve this issue without upgrading the library?

This issue is related to an internal unit test failure.
It can't hardly relate to any issue you may have.
If you are facing some problem, please create a new issue or discussion with a full context for your problem and what your expectations are.
