Thanks for your reply and confirmation.
About 18866, the issue has been resolved perfectly, the issue phenomenon
can't
be reappeared after you revised the issue.

For issue 18866, I have checkout the latest workspace and try to the
following command:
asadmin deploy --contextroot test_sample1 test_sample1.war
asadmin deploy --contextroot test_sample1 test_sample2.war
I saw the following when deploying the second one:
remote failure: Error occurred during deployment: Exception while
loading the app : java.lang.Exception: WEB0113: Virtual server [server]
already has a web module [test_sample1] loaded at [/test_sample1];
therefore web module [test_sample2] cannot be loaded at this context
path on this virtual server. . Please see server.log for more details.
Command deploy failed.
The second war is not deployed in DAS case. I confirmed this as follows:
asadmin list-components
test_sample1 <web>
Command list-components executed successfully.
And I can access
http://localhost:8080/test_sample1 and get the result
for the test_sample1.war
For 18861, it is a different issue. It is about "setting" the same
context root for two different wars.
And I have already pointed out the issue in the jira.
