"I can't input Japanese with ""talend open studio"" started on redhat."

I was able to input Japanese without any problems in the Windows environment, but I was unable to input Japanese in the Talend Open Studio that started on Redhat 6.2.

The following steps are performed:

I use ibus as my Japanese IME

In this case, does the Linux version of Talend Open Studio not support Japanese input?
Or is it a language setting problem in the environment?

"Also, if it is a language setting problem in the environment, what other settings do I need besides installing ""Japanese Support""?"

Please let me know if anyone knows.
Thank you for your cooperation.
