Just to confirm, which version are you using?

[jespersmith]

ihmc-java-ros2-communication uses "us.ihmc:ihmc-build:0.14.0"

[calvertdw]

Okay, thanks. I'll fix in the next release.

Putting this here for my notes.

1. Find origin of NPE
2. Handle that situation without crashing
3. Depending on what it is, either warn or continue silently

@jespersmith This must be a result of a specific situation where it tries to search the 1 height and NPEs on something. I cannot reproduce. If you give me the full stack trace I can add a NPE check.

Did not mean to close that.
