Seeing the following error when trying to install Spectrum with GUI on Linux using Xming:
[root@host linux]# GUI mode is not supported : no awt in java.library.path
GUI mode is not supported : no awt in java.library.path
[xcb] Extra reply data still left in queue
[xcb] This is most likely caused by a broken X extension library
[xcb] Aborting, sorry about that.
java: xcb_io.c:568: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed.
Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)
Upgrade to the latest version of Xming and rerun the installation.
