This is a bug. I'll create a JIRA and link it to this forum thread. Thanks
Thanks for your response. Do you know any workaround until this is fixed?
You would need to ":remove" and ":add" the system property with the new value. Although not required you can run the 2 operations as part of a batch in the CLI:
# batch # /system-property=test:remove # /system-property=test:add(value=newValue) # run-batch
i have installed jboss-as-7.0.2.Final version, i able to added system property through admin console , but not able modify or remove.
can you provide me any alternative for this issue??
