Spring Spring Boot 2.4.* and Java 11

I have a spring boot java app that I trying to port to Java 11. Perhaps due to module system or usage of "internal" API my app fails to start. Here's a portion of the stack trace:

Comment From: qcloop

our application runs with jacoco runtime agent for instrumentation. It turns out it was causing issues, not spring boot. Whoever runs with jacoco runtime agent make sure to run a version compatible with Java 11, which probably be 0.8.7
