Hi there. One of my clients is considering Prefect and someone in their company brought up (in the context of using open source tools) that, at some point, Oracle was planning to charge some licensing fees for pieces of java that were previously open source. They asked me whether Prefect uses components that may rely on java and could be negativelly impacted if there was a change in java licensing. My understand is that the code is all written in Python, but I thought I'd ask anyway. Thanks
