Description of problem:
HttpRemoteEJBJndiBasedInvocationTestCase freeze on pure-IPv6 machines.

This issue is caused by this commit (see JBEAP-10793). Test pass, if I revert this commit and rebuild EAP.

I attached some data before test freeze:

• surefire.thread.dump.txt - thread dump from surefire
• eap.thread.dump.txt - thread dump from EAP
• testcase.output.txt - testcase output

This is regression against EAP 7.1.0.DR19

How reproducible:
70% on pure IPv6 machines

Steps to Reproduce:

1. for (( i = 1; i <= 5 ; i++ )) ; do
      echo "test iteration $i"
      mvn surefire:test@basic-integration-default-web.surefire -B -Dmaven.repo.local=$MAVEN_REPO_LOCAL -fae -Dmaven.test.failure.ignore=true -s $SETTINGS_XML -llr \
       -Dipv6 -Dts.noSmoke -Dts.basic -Dtest=HttpRemoteEJBJndiBasedInvocationTestCase -DtestLogToFile=false
   done
