             Summary: OAuth2SaslClientV10Test or OAuth2SaslClientV11Test intermittently fails during MockWebServer binding
                 Key: ELY-1529
                 URL: https://issues.jboss.org/browse/ELY-1529
             Project: WildFly Elytron
          Issue Type: Bug
          Components: Testsuite
    Affects Versions: 1.2.0.Final
            Reporter: Ondrej Lukas


OAuth2SaslClientV10Test or OAuth2SaslClientV11Test intermittently fails during MockWebServer binding, for example for OAuth2SaslClientV10Test:

{code}
java.net.BindException: Address already in use (Bind failed)
 	at java.net.PlainSocketImpl.socketBind(Native Method)
 	at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:387)
 	at java.net.ServerSocket.bind(ServerSocket.java:375)
 	at okhttp3.mockwebserver.MockWebServer.start(MockWebServer.java:317)
 	at okhttp3.mockwebserver.MockWebServer.start(MockWebServer.java:300)
 	at okhttp3.mockwebserver.MockWebServer.start(MockWebServer.java:289)
 	at org.wildfly.security.sasl.oauth2.OAuth2SaslClientV10Test.onBefore(OAuth2SaslClientV10Test.java:82)
{code}

When this happens it causes only one of test methods to fail. Other tests in OAuth2SaslClientV10Test/OAuth2SaslClientV11Test finish successfully. It seems this test issue is not depended on any platform or JDK.

Part of log when test fails:
{code}
...

...
{code}

It also causes that Exception is thrown during {{@After}} for the same test, example for OAuth2SaslClientV10Test:
{code}
java.io.IOException: Gave up waiting for executor to shut down
	at okhttp3.mockwebserver.MockWebServer.shutdown(MockWebServer.java:375)
	at org.wildfly.security.sasl.oauth2.OAuth2SaslClientV10Test.onAfter(OAuth2SaslClientV10Test.java:88)
{code}

After those exceptions in {{@Before}} and {{@After}} are thrown for some particular test then all following tests works correctly.
