ConnectionPools - Background validation required

SourceForge Submitter: prudrakshala .
Environment: JBoss 3.2.6, JDK 1.4.2_06

"validationQuery" element can be specified for JDBC
connection pools in -ds.xml files. In the current
setup, either we can specifiy "validationQuery" or
remove it. I would like another option of doing the
connection pool validation in a background thread
periodically. The idea is to avoid running
"validationQuery" for every getConnection() which can
consume a lot of time for some applications. I suggest
some thing like:

<backgroundValidationFrequencySeconds>900</backgroundValidationFrequencySeconds>
