With camel-jpa under split(), the transacted camel route requires N loop + 1 JDBC connections

Issue

Let's say camel-jpa is used under split() and it will be invoked 2 times. (2 times loop)
If the max connection pool for JDBC connection is set as 1 and
is used, a request will fail with "Connection is not available".

<route id="get-cat-route">
  <from id="_from2" uri="direct:get-cat"/>
  <setBody id="_setBody1">
    <constant>1,2</constant>
  </setBody>
  <transacted id="_transacted1"/>
  <split id="_split1">
    <simple>${body}</simple>
    <to id="_to2" uri="jpa:org.mycompany.entity.Cat?namedQuery=get_all_cats"/>
  </split>
</route>

error log

Caused by: java.sql.SQLTransientConnectionException: HikariPool-1 - Connection is not available, request timed out after 30002ms.
