Bug ID: 65548
Summary: Webapp context not loaded after calling addServiced,
check and removeServiced calls
Product: Tomcat 9
Version: 9.0.52
Hardware: PC
OS: Linux
Status: NEW
Severity: regression
Priority: P2
Component: Manager
Assignee: dev@tomcat.apache.org

Tomcat's JMX API Navigation
We are currently using Tomcat 9.0.45 and a webapp context can be loaded
dynamically when the following manager JMX operations are called in sequence:
addServiced()
check()
removeServiced().
The same is not happening with Tomcat 9.0.52.
Steps to reproduce:
1) Create a sample webapp (sample.war can be downloaded from here:
https://tomcat.apache.org/tomcat-9.0-doc/appdev/sample/).
2) Turn off autoDeploy in server.xml. For example:
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="false">
3) Start the Tomcat and open manager UI (http://localhost:8080/manager/html).
4) Copy the sample.war (downloaded in step 1) and paste it in Tomcat's webapps
directory.
5) Use jconsole for Tomcat's JMX APIs (Refer attachment).
6) Navigate to MBeans -> Catalina -> Deployer -> localhost -> Operations
7) Click on "addServiced" operation and provide the name of your war file in
the "name" field ("sample" in this case) and click on "addServiced" button.
"Method successfully invoked" popup comes up and click on "OK" button.
8) Similarly, click on "check" operation and provide the same name ("sample" in
this case). Click on "check" button and the same popup described in step 7
comes up. Click on "OK" button.
9) Finally, click on "removeServiced" operation and provide the same name
("sample" in this case). Click on "removeServiced" button and the same popup
described in step 7 comes up. Click on "OK" button.
After these steps, reload Tomcat manager web UI (mentioned in step 3)and the UI
should show the new webapp ("sample" webapp in this case).
The "sample" webapp appears with the Tomcat 9.0.45 but not with Tomcat 9.0.52.
Also tried by replacing "addServiced" operation with the new "tryAddServiced"
operation but the issue is not resolved.
