"Web Page Editor (optional)" package from the Eclipse Galileo/Helios update site has the following very minor quirks in a JSP editor:
- Auto-commenting in Java code fragments does not work (Ctrl /); [fixed in Helios SR2]
- [present in Galileo, fixed in Eclipse Helios SR1] If a Java code fragment has errors that are already fixed, the editor does not remove the error marks until you modify the erroneous place or close/reopen the file being edited;
