Tested on Solaris10u9 and Solaris11 Express.
When swithing to java input method, Control+Space activate hosted IME, instead of the java IME.

Steps to reproduce:
1. Login to ja.UTF-8 or zh_CN.UTF-8 locale, set input method trigger key to Control+Space.
2. Copy WuBi.jar to <jdk_home>/jre/lib/ext
3. Launch Notepad.jar sample.
4. Swith to hosted IM, press Control+Space and compose something. it works fine.
5. Swith to Java IM, select "WuBi Input Method", press Control+Space to activate it.

The Hosted IM is activated, lookup window is displayed when composing, but it's not able to input any text into the notepad.

If the trigger key is set to others, not Control+Space, the switching between hosted IME and java IME works.
