[JBoss JIRA] (WFLY-2209) short versions of command arguments (e.g. -h) are not recognized
by Alexey Loubyansky (JIRA)
Alexey Loubyansky created WFLY-2209:
---------------------------------------
Summary: short versions of command arguments (e.g. -h) are not recognized
Key: WFLY-2209
URL: https://issues.jboss.org/browse/WFLY-2209
Project: WildFly
Issue Type: Bug
Components: CLI
Affects Versions: 8.0.0.Alpha4
Reporter: Alexey Loubyansky
Assignee: Alexey Loubyansky
The validation of command arguments doesn't take into account their short versions leading rejecting the command in case the short versions are used (e.g. -h for --help).

----------------------------------------
Additional testing: This is not just about the automatic prompt to accept unknown certificates, this error is the same if the CLI is configured to use a trust store containing the servers certificate.

> - mvn -PsecondRun exec:java : this runs the second part of the test, which loads the previously saved KieSession from the file and inserts a new fact, resulting in the NPE.
> All three tests can also be run in ReteOO mode by adding "-Ddrools.ruleEngine=reteoo" at the end of the command.

> Issue Type: Bug
> Security Level: Public(Everyone can see)

> I persist a KieSession via the Marshaller (serializable) with one fact/event inserted. On reload of the session, I can see that fact is still there (when I check the FactHandles) and the PseudoClock is at the correct time (the time when I persisted it). If I then insert another fact/event into this reloaded session which matches the following rule:
> rule "SimpleFactTimeWindow"
> when
> $s1: SimpleFact() from entry-point LinkyStream
> $s2: SimpleFact(this != $s1, this after [0s, 10s] $s1) from entry-point LinkyStream
> then
> System.out.println("Rule fired, found 2 Facts within the time window.");
> end
> I get a NPE (in both Phreak and ReteOO mode). Exception in Phreak:

> What I discovered is that this only happens when I save the KieSession to a file in one JVM and reload it in another. When I load the KieSession in the same JVM as the one in which I persisted it, there is no exception and the rule get's fired (as expected).
> I created a reproducer project for it: https://github.com/DuncanDoyle/DroolsSessionPersistenceNPE/
> I've added some Maven profiles so you can easily observe the behaviour:
> - mvn -PallRuns exec:java : this runs both the persistence and the reload in the same JVM, no exception, everything works fine.
> - mvn -PfirstRun exec:java : this runs the first part of the test, and saves the KieSession to a file.
> - mvn -PsecondRun exec:java : this runs the second part of the test, which loads the previously saved KieSession from the file and inserts a new fact, resulting in the NPE.
> All three tests can also be run in ReteOO mode by adding "-Ddrools.ruleEngine=reteoo" at the end of the command.
