Bug 55975 User Libraries lose jars after save, load [build path]
I20040324-0800 Saving and then re-loading the saved user library misses some of the jars. Steps: - new workspace, import org.apache.ant as binary - new java project "abc" - on abc: Properties, Buildpath, Libraries, Add Library - User Library, Next, User Libraries - New: "Ameisen" (not system) - Add Jars... - add ant.jar and ant-antlr.jar from org.apache.ant/lib - Save... into ameisen.userlibraries - Load... from ameisen.userlibraries, load "Ameisen" -> only ant-antlr.jar is loaded -> cannot remove ant-antlr.jar (no reaction, log empty)
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/UserLibraryPreferencePage.java
File file= new File(fLocationField.getText());
				if (!file.equals(fLastFile)) {
					fLastFile= file;
					try {
						List elements= loadLibraries(file);
						fExportImportList.setElements(elements);
						fExportImportList.checkAll(true);
						fExportImportList.setEnabled(true);
						if (elements.isEmpty()) {
							return new StatusInfo(IStatus.ERROR, PreferencesMessages.getString("UserLibraryPreferencePage.LoadSaveDialog.error.empty")); 
						}
					} catch (IOException e) {
						fExportImportList.removeAllElements();
						fExportImportList.setEnabled(false);
						return new StatusInfo(IStatus.ERROR, PreferencesMessages.getString("UserLibraryPreferencePage.LoadSaveDialog.error.invalidfile")); 
					}
