Re: Memory Problems with mysql-connector-java-5.1.6-bin.jar

[Richard Huntrods]

OK. In a way, I've fixed the problem. I checked my source code, and I'm now issuing the correct close() statements as required, so the memory leak is a puzzle.

BUT - I went back through past versions of the jdbc connector because *** this application used to work without any problems ***. Here's what I found. (GOOD means no memory leaks at all - even under extended testing; BAD means memory leaks immediately).

GOOD:

mysql.jar (221 kb, 10/7/2003)
mysql-connector-java-3.0.16-ga-bin.jar (231 kb, 11/16/2004)
mysql-connector-java-3.0.17-ga-bin.jar (241 kb, 6/22/2005)

BAD (memory leak):

mysql-connector-java-3.1.10-bin.jar (409 kb, 6/23/2005)
mysql-connector-java-3.1.14-bin.jar (449 kb, 10/18/2006)
... (other versions)
mysql-connector-java-5.1.6-bin.jar (687 KB, 3/5/2008)

So - does anyone know what the major change was between 3.0.17 and 3.1.10 that would have such a dramatic effect?

Cheers,
