net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::5.0.1 object name already exists: ���� - ucanaccess

Question

I'm trying to run this:
Properties prop = new Properties();
prop.put("user", "");
prop.put("password", "LX2008");
conn = DriverManager.getConnection(
"jdbc:ucanaccess://C:/Users/lh/Desktop/all_num.mdb;jackcessOpener=com.zhangmingge.access.CryptCodecOpener", prop);
But got this:
17:52:47.879 [main] DEBUG com.healthmarketscience.jackcess.Index - unsupported collating sort order SortOrder[2052(0)] for text index (Db=all_num.mdb;Table=MSysObjects;Index=0), making read-only

Bacause there is a table with Chinese name in my database, I guess:
I read this post, but unfortunately, I can't rename the table because another system need it.
Tryed to google, and got this post, but is not the expected solution.
