rdhabalia opened a new pull request #7252:
URL: https://github.com/apache/pulsar/pull/7252
### Motivation
We create a websocket proxy bundle as separate deployment without depending
on broker or any other components. Right now, websocket proxy fails at startup
with below error:
This is failing because websocket requires `jersey-hk2` into classpath to
start webserver but it's not failing with `./bin/pulsar websocket` because it
keeps broker's dependent jars into the classpath and it already has required
`jersey-hk2` in the classpath.
