--------------------------------------------

[~chiba] I had time to test the fix you mentioned. It solves the issue I was experiencing. Does a new Javassist release is planned soon?

> We are using Javassist for one of our open source projects since about 10 years. Recently, I have tried to upgrade to version 3.19 and 3.20. Unfortunately, with both versions, generated byte code seems to cause errors with the JVM.

> The issue seems related to default methods introduced in Java 8. Perhaps its not an issue with Javassist but to be honest I don't understand the exception.  However, I have noticed that using Javassist in version 3.18.2 solves the problem.
