How to repeat:
insert the string \'{{}  to a text field using jdbc (mysql-connector-java-3.0.10-stable-bin.jar).

Two things you should be aware of. First, the escape processing in Connector/J 3.0.11 and newer is better, so that might fix it.

In any case, '{' is a _reserved_ character in JDBC unless is is _inside_ a '' sequence, so you need to escape it with '\', or alternatively turn off escape processing altogether by calling .setEscapeProcessing(false) on the statement in question.

I close this report as "Can't repeat" because there is no feedback for a long time and codebase is too old. Please, feel free to reopen it if the problem still exists in current driver.
