The current implementation on type conversion in Javet carries little performance overhead because container objects have to be created for primitive types regardless of their being used or not.

The idea is to replace it with java.nio.ByteBuffer so that the performance overhead can be minimized. Especially, if the value is not used, there's no memory copy.

Description

Supporting JSR 223 has been requested by a few Javet users. Currently, it is in the backlog because development resource is on some higher priority issues, and there hasn't been a strong demand.

So, if you want this feature, please raise your voice.
