Bug 37249 Export Javadoc does not give any error when the path to javadoc.exe is bogus
Version: 2.1.0 Build id: 200303272130 I had a bogus path to javadoc.exe in Preferences/Java/Javadoc. When I clicked Finish in the Export/Javadoc wizard, nothing happened. I gave up using the feature until today when I ran accross my bad Preference setting. Obviously, the wizard needed to give the user some kind of error message. (FYI, this happened when I upgraded my set up from Sun's 1.4.1_01 to 1.4.1_02.)
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/javadocexport/JavadocWizard.java
URL newURL= fDestination.toFile().toURL();
				List projs= new ArrayList();
				
				for (int i= 0; i < projects.length; i++) {
					IJavaProject iJavaProject= projects[i];
					URL currURL= JavaUI.getProjectJavadocLocation(iJavaProject);
					if (!newURL.equals(currURL)) { 
						
						
						projs.add(iJavaProject);
					}
				}
				if (!projs.isEmpty()) {
					setAllJavadocLocations((IJavaProject[]) projs.toArray(new IJavaProject[projs.size()]), newURL);
				}
			} catch (MalformedURLException e) {
				JavaPlugin.log(e);
			}
