Garbled error message in debug log

[moriyama]

CCOBOL source code pre-compiled with the ocesql command of Open Cobol ESQL for the COBOL to C translator will produce an error at runtime when compiled using the cobj command of opensource COBOL 4J which is a COBOL to Java transrator.

At this time, if you set "debug" in the OCDB_LOGLEVEL environment variable, the log will be output to the /tmp/ocesql.log file, but the error message is garbled.

Steps to Reproduce:

1. Install PostgreSQL Server and create testdb database.
2. Pre-compile the sample INSERTTBL.cbl using ocesql command of Open Cobol ESQL for the COBOL to C translator.
3. Compile the pre-compiled COBOL source code using the cobj command of opensource COBOL 4J which is a COBOL to Java transrator.
4. Set the LANG environment variable to ja_JP.UTF-8.
5. Set the OCDB_LOGLEVEL environment variable to "debug".
6. Run INSERTTBL.

Actual results:

Garbled error messages in /tmp/ocesql.log.

/tmp/ocesql.log:

MESSAGE:[B@29a5f4e7
-9999:08006:[B@29a5f4e7

Expected results:

Error messages are output to /tmp/ocesql.log in Japanese with UTF-8 encoding.
