I have two bugs to report as follows.

===========================================
Firstly: uDig for both Windows and Mac cannot be started up smoothly.

Phenomenon:

Mac: udig-2.0.0.RC1.macosx.cocoa.x86_64

I downloaded the dmg file, and drag uDig to /Application directory. Then I click "uDig", trying to launch it. However, uDig quitted immediately. Even the icon could not be seen in Dock.

Then I browse "/Applications/udig/udig.app/Contents/MacOS", and then directly launch "udig_internal". Then uDig finally launched sucesuflly. But there is several error messages listed below:

===== Message begin ======
2017-12-14 18:01:17.417 udig_internal[4992:752450] [JRSAppKitAWT markAppIsDaemon]: Process manager already initialized: can't fully enable headless mode.
log4j:WARN No appenders could be found for logger (hsqldb.db.HSQLDB4AD417742A.ENGINE).
log4j:WARN Please initialize the log4j system properly.
objc[5605]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fffa5f90b68) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x119e60cd8). One of the two will be used. Which one is undefined.
===== Message end ========

Windows:udig-2.0.0.RC1.win32.win32.x86_64.exe

Windows version acted quite the same. I installed uDig, but I cannot see program information in "Uninstall or Modify program" page of Windows Control Panel.

Then I clicked on "uDig" icon in "Start" menu folder. A console flash up and out, but nothing appeared. I look into task manager and found a process named "udig_internal". Its memory usage kept increasing, but suddenly disappeared as it increased to about 60kBs.

Then I try the "console" way as Mac ver. I open the directory where uDig was installed with control. then I executed "dig.bat". Finally, uDig launched sucefully.

===========================================
Secondly: uDig could not open my she file, no mater Windows or Mac ver.

My operation steps: File -> Open Map -> Select my .shp file -> Open

Then uDig told me: "An unexpected error occurred while reading the map file. Pleas send error log."

What happened? I don't think there is anything error in my .shp file because they were successfully imported by GEOServer and displayed correctly. Meanwhile, uDig mentioned "error log", but I did not know where to find it.

Could you please help me to solve these problems? Thank you at advance!
