A DESCRIPTION OF THE PROBLEM :
When pasting content from Gtk clipboard, the code in the two C++ methods
  - Java_com_sun_glass_ui_gtk_GtkSystemClipboard_popFromSystem
  - get_data_raw(JNIEnv *env, const char* mime, gboolean string_data)
make the assumption that 'text/???', and specially 'text/html' are UTF-8.

When Firefox pastes content, it is encoded in UTF-16. This fact can be easily detected with the leading BOM sequence (FE FF).

A workaround is to use the AWT Toolkit Clipboard manager. It lets the user decide how to decode the clipboard contents.

This is the probable cause of bug 8133337
