FULL PRODUCT VERSION :
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
OS X 10.13.2

A DESCRIPTION OF THE PROBLEM :
Setting a FileDialog to visible raises the following exception:

objc[656]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fffa439fb68) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x1208e8cd8). One of the two will be used. Which one is undefined.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the following code:

FileDialog fd = new FileDialog(new Frame(),"Open Dialog Test",FileDialog.LOAD);
fd.setVisible(true);

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The file dialog opens without issue.
ACTUAL -
The dialog opens, but the exception described above is raised (I believe from Xcode) corrupting the Java process and leading to unpredictable application behavior.
