I'll look into it, thanks!

Likely means that there are some classes in classpath that were compiled for old or new java bytecode version

@robfletcher Ranie is working on fix https://github.com/spekframework/spek/pull/471

[robfletcher]

cool

[robfletcher]

It's interesting it only happens to me in IntelliJ. It's using the same JDK as my terminal so I'm not sure why there's a discrepancy.

[robfletcher]

it appears that the generation of that volume of logging slows the test run down appreciably!

[artem_zin]

Likely IntelliJ adds something invalid for reflections to the classpath

@robfletcher 2.0.0-alpha.2 is out, hopefully it fixes your issue 🤞
