Description:
with this url:

sql.url                   = jdbc:mysql://${sql.host}/${sql.database}?autoReconnectForPools=true&prepStmtCacheSize=50&cachePrepStmts=true&elideSetAutoCommits=true&useLocalSessionState=true&profileSQL=false&useUsageAdvisor=false&gatherPerfMetrics=true

I get this exception when using getGeneratedKeys:

 java.lang.NullPointerException
	at com.mysql.jdbc.ResultSet.<init>(ResultSet.java:366)
	at com.mysql.jdbc.Statement.getGeneratedKeysInternal(Statement.java:1157)
	at com.mysql.jdbc.Statement.getGeneratedKeys(Statement.java:1120)
	at com.mysql.jdbc.PreparedStatement.getGeneratedKeys(PreparedStatement.java:1483)
	at org.apache.commons.dbcp.DelegatingStatement.getGeneratedKeys(DelegatingStatement.java:305)
	at org.apache.commons.dbcp.DelegatingStatement.getGeneratedKeys(DelegatingStatement.java:305)
...

it appears that the tableName at that line is null.

How to repeat:
happens every time getGeneratedKeys() is called on a prepared statement to retrieve the generated keys after executing the ps update.

turning off the perfMetrics option fixes the NPE
