Steps to reproduce (Required on creation)

update version of Camunda from 7.21.0 to 7.22.0 in Dockerfile

Observed Behavior (Required on creation)

Java Process Application is deployed, but "not started", Processes and forms are not deployed. the included "camunda-invoice" process application starts up normally. if the application is "recompiled" from the current github repo (tag 7.22.0), the invoice app does not deploy either!

Expected behavior (Required on creation)

Java Process Application should be deployed AND also start and deploy processes/forms in Camunda 7.22.0

Root Cause (Required on prioritization)

I dont know why it happens

Solution Ideas

Downgrade to 7.21.0

Hello @tvhdev , thanks for the report. This might be related to some upgrades in version 7.22, I suggest you check the 7.21 to 7.22 Migration Guide, for example the Tomcat 10 upgrade which mentions updating javax dependencies. If the issue persists, it could be useful to share the logs you get when the application isn't started.
