A very strange problem in microsoft access

Question

Hi all,
Recently I wrote a simple java application which use microsoft access as the database. I connect the database sucessfully and I've even done the regular expression to filter the invalid text characters, everything works fine util I do the following SQL:
insert into test values 'client for updates'
Here test is my table name
I found this perticular string 'clent for updates' is very strange, it can't be inserted into the database, I try 'client for up' or something else, they all work.
Could anyone tell me what happened?
With my best,

My problem is, even I've written the SQL in the correct syntax, in my java code, it just look like this
adc.SQL("insert into test(subject, content) values('" + sf.filter(subject.getText()) +"'"
                              + "," + "'"
                              + sf.filter(board.getText()) + "')" );
                              subject.setText("");
                              board.setText("");
where subject is a textfield and board is a JTextArea and sf is a string filter which use regular expression, I basically want to insert the string in these component into the database, Many strings work, but client for updates can't be inserted.
