<p style='margin-top:0;margin-bottom:10px;'>After having a closer look at the code I think i have figured out what causes this. The code tries to call PrepareStatement.setBinaryStream(int, InputStream, long). This method was added in JDK1.6 but C3P0 implements just the JDK1.5 API and there it just exists as (int, InputStream, int). But as far as I know Hibernate doesn't require JDK 1.6</p>
<p style='margin-top:0;margin-bottom:10px;'>The first idea was that BlobTypeDescriptor was changed. But that was not true. </p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java"><span class="code-keyword">public</span> <span class="code-keyword">static</span> <span class="code-keyword">final</span> BlobTypeDescriptor STREAM_BINDING =
<span class="code-keyword">new</span> BlobTypeDescriptor() {

<span class="code-keyword">throws</span> SQLException {
<span class="code-keyword">final</span> BinaryStream binaryStream = javaTypeDescriptor.unwrap( value, BinaryStream.class, options );
st.setBinaryStream( index, binaryStream.getInputStream(), binaryStream.getLength() );
}
};
}
@Override
<span class="code-keyword">public</span> <X> BasicExtractor<X> getBlobExtractor(<span class="code-keyword">final</span> JavaTypeDescriptor<X> javaTypeDescriptor) {
<span class="code-keyword">return</span> <span class="code-keyword">new</span> BasicExtractor<X>( javaTypeDescriptor, <span class="code-keyword">this</span> ) {

<span class="code-keyword">return</span> javaTypeDescriptor.wrap( rs.getBinaryStream( name ), options );
}
};
}
};</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>But after some time I figure out that signature of BinaryStream.getLength() was changed so that it returns an long instead of an int now. When you compile BlobTypeDescriptor with the new BinaryStream class that works well but it means that it will try to call a different JDBC API now. And this API doesn't exist in JDK 1.5 yet.</p>
<p style='margin-top:0;margin-bottom:10px;'>This is a smilar problem like in <a href="https://hibernate.onjira.com/browse/HHH-7778" title="Hibernate does not work anymore with c3p0">HHH-7778</a></p>
