Mac上写JavaFX报错
objc[37877]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fffaa1563c8) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x13df3df50). One of the two will be used. Which one is undefined.
大概意思是一个类实现了两次，有其中一个被使用，不影响使用，只是提示信息
