There was a problem hiding this comment.
This is still broken because it just copies the evmc_result struct, but the pointers to output are left loose. We need to move to a proper Java Result class, i.e. #555.
However, the PR does not change semantics.

It's been a while. Happy to approve this PR as it seems relatively small, but I have a hard time recalling all the context. If it helps land #555 that's great. |

This could be replaced with just passing buffers allocated based on #555.
Part of #548.
