[jbosstools-issues] [JBoss JIRA] (JBIDE-11666) Add -XstartOnFirstThread as a command line argument for Mac

[Lucia Jelinkova (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-11666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12688403#comment-12688403 ] 

Lucia Jelinkova commented on JBIDE-11666:
-----------------------------------------

Basically, every test plugin overrides the systemProperties property in order to propagate some arguments to the Eclipse launched by Tycho. For example the location of configuration file or configuration of SWTBot. SWTBot also contains functionality of replacing environmental variables in the property files - these are passed as well. 

Example:

> I've found out that the Display needs to be created on thread 0 - this can be accomplished by adding -XstartOnFirstThread as a VM argument. However, the VM on Linux cannot handle the parameter, so it needs to be specified only for Mac. 
> In order not to repeat the configuration in every test module. Could you please provide a new profile in parent pom activated for Mac that would add the mentioned parameter to the tycho-surefire-plugin's argLine property?
