h1. *I have additional info to this issue:*
*I have unsuccessfully tried to resolve this issue by editing the *ExamplesOperator.java* class, see the details below:*


*Path to the edited java file*: central/test-framework/org.jboss.tools.central.reddeer/src/org/jboss/tools/central/reddeer/api/ExamplesOperator.java


*Performed changes (output from the git diff):*
 !first_unsuccessful_attempt_to_fix_this_issue.png|thumbnail! 


*Result of my trial:* Issue still remains, performed changes does not affect the result, after the run of WildFly example itests there are same amount of occurrences of this issue after the test has finished. I am gonna remove this changes completely, it does not help to resolve this issue.
