Schema from JavaBeanSchema causes stack underflow

Minimum example: [https://github.com/akettmann-e24/beamErrorExample](https://github.com/akettmann-e24/beamErrorExample)

Runner: DirectRunner

Tested under JVMs:
* AdoptJDK Java 11.0.10
* AdoptJDK Java 11.0.11
* Oracle Java 1.8.0.262

Tested under beam version:
* 2.28.0
* 2.29.0

When using a schema with a JavaBeanSchema, if a field is an `Java.time.Instant`, pipeline fails once the value has been returned and the return value needs to be encoded into a ByteArray. Stack trace below:

Slightly different stack trace when it is from a ParDo returning a type that has a schema inferred, but the same end result of a stack underflow.
