It seems we need an API method to work around a severe Swing bug in a common way. See issue #46014 for details.
Created attachment 16397 [details] Proposed addition to FileUtil, plus example of its application to the Open Project dialog (tested and functional in contrast to the unpatched Add Favorites dialog, tried on Linux under 1.4.2_04 Metal, 1.5.0 b58 Ocean, 1.5.0 b58 GTK)
Note #1: might be necessary to have the method actually take a File currentDirectory (optional, may be null), and if non-null wrap it before setting it. Otherwise it seems that while you can select a noncanonicalized symlink dir to open a project from, the persisted default directory for the dialog gets set as a plain java.io.File on the file chooser, causing the path to get "polluted" with an unwrapped File temporarily, so that the dialog opens with the canonicalized path. You can browse to the uncanonicalized path, so this is only a minor annoyance. Note #2: of course if and when the Swing bug is fixed, we can patch the method to do nothing for fixed JREs; and when we take as a minimum a JRE which already has the fix, we can just make the method do nothing and deprecate it. Note #3: I put the method into FileUtil rather than Utilities since it does depend on the normalizeFile method and separation of openide dictates that Utilities should not depend on FileUtil.
No objections; I will commit it.
