Hello,

expected output

Process started with (from Debug):
FINER: Starting server with command: [java, -Dsetting1=x, -Dsetting2=y, -javaagent:lib/bootstrap-agent.jar, -jar, lib/ws-launch.jar, defaultServer]

actual output

note the missing comma betweed setting1 and setting2:
FINER: Starting server with command: [java, -Dsetting1=x -Dsetting2=y, -javaagent:lib/bootstrap-agent.jar, -jar, lib/ws-launch.jar, defaultServer]

Solution

Already exists. This commit is currently not in a release:
https://github.com/arquillian/arquillian-container-was/commit/a1a77fe92418f49943a97a57a4dd1ff7ebc2bd25#diff-957685487719c29ce4c464fc2ec9cf39

What can't be seen from here: this commit is needed to have multiple JVM args. Otherwise all jvm args are concatenated into a single String.

So, the bug is fixed in trunk, but not released.

Proposed test case

It is also missing a test case.
Please add a test case with two or more -D-Parameters and check in your servlet if they are set.

Thank you very much!
