> oVirt is using jboss-modules not only for dependencies inside WildFly, but also when executing command line tools outside WildFly process. We are using following method which worked fine from JBoss 7 to WildFly11:
> export JAVA_MODULEPATH="<PATH TO OUR MODULES>"
> exec "${JAVA_HOME}/bin/java" \                                                                                                                                                                                
>         -jar "${JBOSS_HOME}/jboss-modules.jar" \                                                                                                                                                              
>         -dependencies org.ovirt.engine.core.tools \                                                                                                                                                           
>         -class org.ovirt.engine.core.cryptotool.Main \                                                                                                                                                        
>         "$@"
> where "org.ovirt.engine.core.tools" is one of our existing module and in class we have standard Java class with main() method executing logic of specific command line tool.
> When I try to execute this code with WildFly 12.0.0.FINAL I receive following exception:
> Exception in thread "main" java.lang.NullPointerException
> 	at java.util.Hashtable.put(Hashtable.java:460)
> 	at java.util.Properties.setProperty(Properties.java:166)
> 	at java.lang.System.setProperty(System.java:796)
> 	at org.jboss.modules.PropertyWriteAction.run(PropertyWriteAction.java:40)
> 	at org.jboss.modules.PropertyWriteAction.run(PropertyWriteAction.java:28)
> 	at java.security.AccessController.doPrivileged(Native Method)
> 	at org.jboss.modules.Main.main(Main.java:390)
> When I tried to replace jboss-modules.jar provided by WildFly 12.0.0.FINAL with manuall build using latest code in 1.7 branch (commit a52a323c5c3d71cf9597f06951155e4639cbb707) I receive different error:
> org.jboss.modules.ModuleNotFoundException: org.ovirt.engine.core.tools
> 	at org.jboss.modules.Module.addPaths(Module.java:1221)
> 	at org.jboss.modules.Module.link(Module.java:1577)
> 	at org.jboss.modules.Module.relinkIfNecessary(Module.java:1605)
> 	at org.jboss.modules.ModuleLoader.loadModule(ModuleLoader.java:296)
> 	at org.jboss.modules.Main.main(Main.java:426)
> I haven't found any documentation describing such incompatible between 1.6 and 1.7, so is there any way how to have above execution compatible with both jboss-modules versions?
> Thanks
