Last updated on JULY 18, 2018

Applies to:

JDBC - Version 12.1.0.1.0 and later
Information in this document applies to any platform.

Symptoms

Oracle JDBC/thin 12.1 drivers  do not retrieve a CLOB value correctly when the size is exactly 8000 and the character set is a UTF-8 character set such as AL32UTF8.

Typically when the issue occurs you will find expected NULL characters inserted in the data.
