Jersey 2.34 with HTTPS and PATCH method fails with error when run with JDK 16

Configuration:
- JAX-RS client API
- Jersey 2.34 as the JAX-RS provider
- REST service utilizing HTTPS and the PATCH method
- JDK 16

This configuration implies that the default `HttpsUrlConnection` is used as the connector.

When making a PATCH request to the REST service with this configuration, the PATCH request fails with the stack trace shown below. JDK versions up to and including JDK 15.0.2 work successfully with the same configuration. Could work around using a different connector, if willing to use Jersey-specific API to specify the connector implementation.

Stack trace:
```
