Strange hibernate exception when running under Linux

I have a project that compiles and runs completely fine under OS/X, but under Linux an exception is thrown that gives no clue as to what might be the problem. I've been stuck on this for hours trying to narrow it down, any pointers would be helpful!

The environment that I am having trouble under is

• OS: Ubuntu 10.4 and/or Ubuntu 8.4
• Java: Ubuntu sun java package and/or latest java 1.6 downloaded from Oracle
• Hibernate: version 3.5.4

The relevant part of the persistence.xml file is as follows:

<persistence-unit name="testing">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>package.grssc.model.Application</class>
    <class>package.grssc.model.ExternalPerson</class>
    <class>package.grssc.model.Organisation</class>

        <property name="hibernate.connection.url" value="jdbc:hsqldb:mem:unit-testing-jpa" />
        <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="create-drop" />
        <property name="hibernate.connection.username" value="sa" />
        <property name="hibernate.connection.password" value="" />
    </properties>
</persistence-unit>

I have been doing some digging into the source code, and it doesn't help. It appears there is some unsafe code in hibernate:

/**
 * Get the JAR URL of the JAR containing the given entry
 * Method used in a non managed environment
 *
 * @param url URL pointing to the known file in the JAR
 * @param entry file known to be in the JAR
 * @return the JAR URL
 * @throws IllegalArgumentException if none URL is found
 */
public static URL getJarURLFromURLEntry(URL url, String entry) throws IllegalArgumentException {
    URL jarUrl;
    String file = url.getFile();
    if ( ! entry.startsWith( "/" ) ) entry = "/" + entry;
    file = file.substring( 0, file.length() - entry.length() );

If the url parameter is a shorter string than the entry parameter, then an exception occurs. Not sure I have done it right, but here is the output when i set the log level to debug:

What about case-sensitiveness of file names? I'm not familiar with OS/X's file system, but maybe it's just a filename with another case as in the persistence.xml?

This could explain, why it doesn't work on linux.
