OCI, java.lang.ArithmeticException: / by zero

Question

Hi,
Could someone help me with this?
I'm using OCI driver, because database character set is user-defined.
There is no problem with connection, but if I open any database objects list or execute any statement I've got this exception:
Oracle SQL Developer 1.5.5:
java.lang.ArithmeticException: / by zero

Oracle SQL Developer 2.1.1.64:
Level Sequence Elapsed Message
SEVERE     99     2448498          / by zero
I dig into JVM using VisualVM and find out that oracle.jdbc.driver.T2CConnection.conversion (DBConversion.java) has property sMaxCharSize=0.
When I'm connecting to other DB (wihtout user defined charset) this property has value 1 and everything is ok.
Other DB tools like Squirell SQL, PL/SQL Developer works fine so maybe there is a bug in Oracle SQL Developer?.

Answer 1

This seems more like a bug in the JDBC driver than in SQL Developer itself.
Try replacing the JDBC driver in SQLDEVELOPER_INSTALL_DIR\jdbc\lib with the very latest version from OTN.
You may also want to try upgrading your OCI client to latest and if you still got the problem then better raise a SR on Metalink/MOS if you have a DB support contract.
