**Elasticsearch version** : 7.3.1

**APM Server version** : 7.3.1

**APM Agent language and version** : JAVA agent 1.9.0

**Websphere Application Server version** : 8.5.5.0, Single cell-node-server configuration.

**Description of the problem** : Websphere fails to startup with `startServer.cmd` script when Java agent is installed.

We are attempting to monitor performance of a java application deployed in this appserver using the APM java agent.  
Following [this](https://www.elastic.co/guide/en/apm/agent/java/current/setup-javaagent.html#setup-websphere-liberty) guide, we added the following generic arguments to the appserver:

```
-javaagent:D:/WAS/lib/elastic-apm-agent-1.9.0.jar
-Delastic.apm.service_name=my-apm-service
-Delastic.apm.application_packages=com.my.app.package
-Delastic.apm.server_urls=http://localhost:8200

```

However, when attempting to start up the local server using the startup script it fails and generates the following errors in the logs:

```

Hi and welcome to the forum!  
WebSphere Application Server is [not supported yet](https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html#supported-app-servers), only WebSphere Liberty.  
We _do_ intend to support it, but there is no concrete schedule for that yet.
