Java MIP SDK 1.17.154: commitAsync() TemplateNotFoundError (C# OK; Java fails Win & Ubuntu)

I ran into this same problem in C# w/ version 1.17.137.  Upgraded to 1.17.154 and 1.17.158 and the issue is still there  Had to roll back to 1.16.159 to get around it.  The problem occurs when attempting to commit a label to a file, when that label has an encrypted protection template applied to it.  Seems like a breaking change may have been introduced in 1.17.x somewhere in the C++ code.  I didn't see any mention of a change in protection behavior in the release notes for 1.17.x.  I hope someone on the SDK team catches and fixes this, or I'll be unable to upgrade my package past 1.16.159.  Please help!
