Description

After start tika-app-1.24.1 using: java -jar tika-app-1.24.1.jar -g from an linux terminal to open the Tika GUI window. As soon as open a pdf file containing CJK characters from the Tika App GUI, received the following error messages. Please note opening the same file in tika-app-1.23 execute perfectly as expected without these errors. 

Also downloaded and compiled the Tika-Master, I believe it's the unreleased tiks-2.0.0. The same problem above is present as well. 

I also received (java:10218): GLib-GObject-WARNING **: 11:21:32.098: invalid cast from 'GtkToplevelAccessible' to 'JawToplevel' in the terminal in both cases.
