Under SPARC/Intel j2se JDK1.3.1_02, ja locale, JTextField causes
an IllegalArgumentException when user pastes a text if there is
a preedit string of converison. Implicit commit should be functioned.

To reproduce:
1)
% javac Sample.java
2)
% java Sample
3) Conversion-on for Japanese input
4) input something such as 'aiueo' and does not commit the string
5) Paste some text into the JTextFiled
-> It makes IllegalArgumentException.
