Hi All,

A related issue, as per 

we support 3 styles, /On-the-spot, ///Below-the-spot and /////Root-window.
////The framework chooses between on-the-spot and below-the-spot input 
for active clients based on a system property or an AWT property 
"java.awt.im.style". The system property can be defined from the command 
line (by the end user), the AWT property in a localized awt.properties 
file (by the localizer or a system administrator). If both are defined, 
the system property takes precedence.

/But specifying /-Djava.awt.im.style=root-window/, does not create a 
separate composition window for say, Japanese. Similarly, specifying 
/-Djava.awt.im.style=On-the-spot /for Chinese still creates separate 
sogou composition window. Is that a bug or is this command line has a 
different meaning?
