JdbcSupportLoader throws AbstractMethodError on JDBC < 1.4
----------------------------------------------------------

                 Key: HHH-5459
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5459
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.6.0.Beta2
            Reporter: Stephane Epardaud


When using a legacy JDBC driver before Java 1.4 I get the following exception:

{noformat}
Caused by: java.lang.AbstractMethodError: solid.jdbc.SolidDatabaseMetaData.getJDBCMajorVersion()I
        at com.mchange.v2.c3p0.impl.NewProxyDatabaseMetaData.getJDBCMajorVersion(NewProxyDatabaseMetaData.java:3726)

{noformat}

Which is due to the fact that JdbcSupportLoader invokes DatabaseMetaData.getJDBCMajorVersion() which was introduced in Java 1.4.

Would it be possible to check for the presence of this function so that we can keep using legacy drivers which in our case is the only way to keep working with this obsolete database (Solid)?
