And http://extensions.libreoffice.org/extension-center/languagetool states that version 2.3 of LanguageTool requires Java 7 now. So it is likely that the code actually makes use of features only available in Java 7, and was not only by accident compiled without a --target=6 switch. Though, of course, the rather cryptic error message when trying to install it is not optimal...

(for more informations, see http://en.wikipedia.org/wiki/Java_class_file#General_layout, which gives a helpful list of major version for java class files amongst other things). As for your issue, switching to Java7 is likely to fix it, and unlikely to break anything. Although mishap can happen, Java is usually quite nice with retrocompatibility (in case you have anything in LibreOffice that actually use Java beside languagetool...). -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
