=======================================================================
When type "java t11", it just run to draw a English string, first line
on the canvas is to draw this string horizontally, but it show a strange
string. The second line is to draw it with rotating a angle, the string
is shown correctly, but has no angle. When typing "java t11 2" in zh loca,
it wiil run to draw a string containing Chinese, exception will be caught.
The ecception is as follows:

Exception occurred during event dispatching:
