custom messages with fixed-length arrays is received in rosjava as an empty array

[samuelba]

I discovered an issue with messages containing an array with a fixed (predefined size).

Message example that is not working:

string[5] names

Message example that is working:

string[] names

If I subscribe in rosjava (Android) to the first message, I always get an empty names array with size zero. However, if I publish the second message with dynamic size 5 (filled with names.push_back("name");) I get the correct size with the content.

Is this a known limitation? Or just a bug?

@samuelba sorry for such a late response but I am pretty sure this is a bug.
Today I submitted a fix for this that may be close to fixing what you reported.
I am closing this bug here as the other repo where you reported the issue (https://github.com/rosjava/rosjava_bootstrap/issues/520) is more appropriate.
