The getIDString() method of the java.awt.GraphicsDevice class is a String
whose contents are not specified or discussed in the documentation.

We should clarify that the contents of the string and its format are not
generally programmatically useful and that different vendors may format
their return values in different ways. The programmer can use the string
as is for debugging purposes, but if they wish to examine the contents and
act on them, then they should consult the documentation of the VMs from the
various porters and check the "java.vendor" system property at runtime to
determine how to interpret the string.
