<p>don't know if this thread is still in progress but I have found something interesting in my case.</p>

<p>I have and old project using hibernate 3.2 and I update it to the last version (hibernate 4.1.4)</p>

<p>In this project no webflow, just jsp/mvc.</p>

<p>Spring 3.1.1<br/>
Hibernate 4.1.4<br/>
c3p0 0.9.1.2</p>

<p>I have the same issue : connections do not return to the pool.</p>

<p>I notice that I've change my pom.xml from : </p>

<p>&lt;dependency&gt;<br/>
 &lt;groupId&gt;c3p0&lt;/groupId&gt;<br/>
 &lt;artifactId&gt;c3p0&lt;/artifactId&gt;<br/>
 &lt;version&gt;0.9.1.2&lt;/version&gt;<br/>
&lt;/dependency&gt;</p>

<p>To : </p>

<p>                &lt;dependency&gt;<br/>
                        &lt;groupId&gt;org.hibernate&lt;/groupId&gt;<br/>
                        &lt;artifactId&gt;hibernate-c3p0&lt;/artifactId&gt;<br/>
                        &lt;version&gt;${org.hibernate.version}&lt;/version&gt;<br/>
                        &lt;type&gt;jar&lt;/type&gt;<br/>
                        &lt;scope&gt;compile&lt;/scope&gt;<br/>
                &lt;/dependency&gt;</p>

<p>When I use the standard c3p0 jar no problem. But when I use hibernate-c3p0 the problem appear.</p>

<p>I think it might depend of how the pool is declared : persistence.xml or bean style.</p>

<p>Hope it helps</p></div>
