Is there a way to detect if there is an uncommitted transaction in H2?

I am using an H2 database with JDBC to create a connection with setAutoCommit(false). I am currently programatically checking whether or not there is an uncommitted transaction, but I was wondering if there was a way to directly query H2 for information about this state. I have found some information for other databases on this topic, but nothing so far on H2.
