Bug 117216 [preferences] Support JDK version 1.6
I'm on 3.2M3. I'm using JDK 1.6 and "Infer Generic Type Arguments" shows an error dialog that this action is only available with Java 5 or better. I think, the problem is that org.eclipse.jdt.internal.corext.util.JavaModelUtil#is50OrHigherJRE only checks for JDK 1.5. I've changed the last line of that method to return javaVersion.startsWith(JavaCore.VERSION_1_5) || javaVersion.startsWith("1.6"); and it seems to work (just a workaround). PS: Once there's a VERSION_1.6 compilance level, is50OrHigher() will also fail...

IJavaProject currProject= elem.getJavaProject(); 
		try {
			
			IJavaModel jmodel= JavaCore.create(ResourcesPlugin.getWorkspace().getRoot());
			IJavaProject[] jprojects= jmodel.getJavaProjects();
			for (int i= 0; i < jprojects.length; i++) {
				IJavaProject curr= jprojects[i];
				if (!curr.equals(currProject)) {
					IClasspathEntry[] entries= curr.getRawClasspath();
					for (int k= 0; k < entries.length; k++) {
						IClasspathEntry entry= entries[k];
						if (entry.getEntryKind() == elem.getEntryKind() && entry.getPath().equals(elem.getPath())) {
							IClasspathAttribute[] attributes= entry.getExtraAttributes();
							for (int n= 0; n < attributes.length; n++) {
								IClasspathAttribute attrib= attributes[n];
								if (IClasspathAttribute.JAVADOC_LOCATION_ATTRIBUTE_NAME.equals(attrib.getName())) {
									return attrib.getValue();
								}
							}
						}
					}
				}
			}
		} catch (JavaModelException e) {
			JavaPlugin.log(e.getStatus());
		}
		return null;
