Description
Beginning with TIBCO BusinessEvents 5.5.0 we support hot deployment of artifacts from Web Studio for In-Memory projects. When user attempts this deployment from Web Studio a NullPointer exception is reported on LoadAndDeploy in WebStudio (Worklist) when hotdeployment is enabled and Object Management is "Memory Only" for deployed TIBCO BusinessEvents application.
Exception in RMS server log:

Issue/Introduction
Hot-deployment failed with NullPointerException for in-memory projects
Environment
All Operating Systems
Resolution
The error is caused by configuration issue.
To hot-deploy artifacts for in-memory projects add property "<project name>.<environment name>.ws.jmx.inMemory" to the RMS server and set it to true for the specific project/environment.
see, Chapter "New Features", "Rule Management Server (RMS)":
https://docs.tibco.com/pub/businessevents-enterprise/5.5.0/TIB_businessevents-enterprise_5.5.0_relnotes.pdf
eg. (For deployed BE project "DTHotDeploy, "QA" environment, deployed and started on "localhost", JMX Port "5555", agent name: "Inference-class"):
