JDBC warning on setAutoCommit(false)

I've got some code that abstracts JDBC connections and does all
kinds of magic for me. One of things it does is, when returning a
connection to the pool, it looks for any SQLWarnings the connection
contains. I've got a few things that begin transactions by setting
autocommit to false, then do some work, then commit (or rollback), and
then set autocommit back to true. When the connection is returned to the
DB, the following warning is issued:

java.sql.SQLWarning: WARNING: COMMIT: no transaction in progress
at org.postgresql.jdbc1.AbstractJdbc1Connection.addWarning(AbstractJdbc1Connection.java:430)
at org.postgresql.core.QueryExecutor.execute(QueryExecutor.java:111)
at org.postgresql.jdbc1.AbstractJdbc1Connection.ExecSQL(AbstractJdbc1Connection.java:482)
at org.postgresql.jdbc1.AbstractJdbc1Connection.ExecSQL(AbstractJdbc1Connection.java:461)
at org.postgresql.jdbc1.AbstractJdbc1Connection.setAutoCommit(AbstractJdbc1Connection.java:942)
[...my code...]

This doesn't seem like the right thing to do...I should be able to
enable autocommit without a warning when a transaction is not in progress.
If anything, I should get a warning is there *is* a transaction in
progress.
