TestBench doesn't work with V14 + Java 16 #1295

Open tarekoraby opened 3 years ago

tarekoraby commented 3 years ago

TestBench doesn't seem to work with the combo of Vaadin version 14 + Java 16.

To reproduce:

Run V14 branch of the skeleton-starter-flow-spring project with Java 16 (tested with Vaadin 14.6.8 + Amazon Correto 16.0.2).

Then execute the tests of MainViewIT. The following errors are observed:

java.lang.IllegalStateException: Unable to create proxy for driver

And to clarify, the same tests work just fine with Java 16 on the same machine with Vaadin 20.0.7
