CAUSE

This problem occurs because of a timing issue inside the just-in-time (JIT) compiler. There is a small time window in which the state of a JIT-activated component is invalid. The assertion is correct. This problem is only apparent with Java components that are called from JScript because of performance optimizations that are made for this scenario.
