Assert-failures surface in shell console.

[kodecharlie]

I wanted to capture this issue in case it represents a real problem, but it may simply have something to do with the my operating environment. Here are some details:

• macOS Mojave 10.14.4
• java 8 (as shown below)

$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Shell console looks like this:

$ java -jar pkg/BioAssayTemplate.jar 
objc[4242]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fff99a2a3c8) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x12df55f50). One of the two will be used. Which one is undefined.
