Hi, I ran across some funny characters appearing in the application title under gnome shell and it turned out to be an old bug.
Bug: https://bugs.openjdk.java.net/browse/JDK-6961123 Webrev: http://cr.openjdk.java.net/~omajid/webrevs/6961123-missing-null-wmclass/00/ The ICCCM [1] states: The WM_CLASS property (of type STRING without control characters) contains two consecutive null-terminated strings. ... Note that WM_CLASS strings are null-terminated and, thus, differ from the general conventions that STRING properties are null-separated. But AWT doesn't do that. It uses two null-separated strings for WM_CLASS. The webrev fixes that.
