Description Kunda 2013-11-15 05:23:25 UTC
FYI This is my first time attempting to use LanguageTool extension so I am not familiar at all if it's working or not.

Running 0SX 10.8.5
Not sure what version of Java
I've just tried to install LanguageTools extention 2.3 on LibreOffice
through first downloading the file LanguageTool-2.3.oxt and then opening it up with LibreOffice. It starts to install and then throws the this at me such as:

(com.sun.star.uno.RuntimeException) { { Message = "[jni_uno bridge error] UNO calling Java method writeRegistryInfo: non-UNO exception occurred: java.lang.UnsupportedClassVersionError: org/languagetool/openoffice/Main : Unsupported major.minor version 51.0\X000ajava stack trace:\X000ajava.lang.UnsupportedClassVersionError: org/languagetool/openoffice/Main : Unsupported major.minor version 51.0\X000a\X0009at java.lang.ClassLoader.defineClass1(Native Method)\X000a\X0009at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637)\X000a\X0009at java.lang.ClassLoader.defineClass(ClassLoader.java:621)\X000a\X0009at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141)\X000a\X0009at java.net.URLClassLoader.defineClass(URLClassLoader.java:283)\X000a\X0009at java.net.URLClassLoader.access$000(URLClassLoader.java:58)\X000a\X0009at java.net.URLClassLoader$1.run(URLClassLoader.java:197)\X000a\X0009at java.security.AccessController.doPrivileged(Native Method)\X000a\X0009at java.net.URLClassLoader.findClass(URLClassLoader.java:190)\X000a\X0009at java.lang.ClassLoader.loadClass(ClassLoader.java:306)\X000a\X0009at java.lang.ClassLoader.loadClass(ClassLoader.java:295)\X000a\X0009at java.net.FactoryURLClassLoader.loadClass(URLClassLoader.java:627)\X000a\X0009at java.lang.ClassLoader.loadClass(ClassLoader.java:247)\X000a\X0009at com.sun.star.comp.loader.RegistrationClassFinder.find(RegistrationClassFinder.java:55)\X000a\X0009at com.sun.star.comp.loader.JavaLoader.writeRegistryInfo(JavaLoader.java:399)\X000a", Context = (com.sun.star.uno.XInterface) @0 } }

Assuming you are referring to LanguageTool-2.3.oxt as available from <http://languagetool.org/>.  Note <http://languagetool.org/issues/>: "For Mac users: LanguageTool now requires Java 7, which is available for the Mac only as a 64 bit version. LibreOffice and OpenOffice are only available in 32 bit, leading to an incompatibility so that LanguageTool cannot be used as an LibreOffice/OpenOffice plugin on the Mac. The only known workaround is to use LanguageTool 2.2, which is still available from the download archive, for which a 32 bit version of Java 6 still exists. LanguageTool 2.2 doesn't require Java 7 but also works with Java 6."
