Evaluator Compiler generate and compile the class code everytime？

The engine compiles string expressions only once, when a new Knowledge instance is created.

You just opened a new issue, what is it exactly? How to reproduce it? If it's not an issue, then I suggest moving it to the Discussions.

i mean in the same JVM process, same string expression can use the same class.

That's exactly what the engine does under the hood whenever it's possible. The default expression parser is just a basic implementation of a SPI (Service Provider Interface), and developers are free to use own implementations of these interfaces.
