Interestingly the GWT team is also [tracking the issue](https://github.com/gwtproject/gwt/issues/8243), albeit it is closed.\r\n\r\nI actually agree with dankurka's comment on the GWT issue (Jun 10, 2015). He's basically saying he cannot understand why the error would ever be emitted, as the [relevant code](https://github.com/gwtproject/gwt/blob/master/dev/core/src/com/google/gwt/dev/shell/CheckForUpdates.java) only use the user nodes, not the system nodes, of the Preference tree. He's right in saying that. When looking at the JDK source for `WindowsPreferences.java` there's no indication that you would get the error *unless* you use the system node. So it is all very strange.\r\n\r\nPerhaps the error isn't really emitted by GWT compiler?  It is rather difficult to track down from where the error comes as there's no stacktrace and I wouldn't know how to force one to be produced. Have tried adding `-Dgwt.logLevel=DEBUG`  to the Maven command. It does produce lots of additional information but none that tells from where the error is coming.\r\n"}}
