The issue stems from the fact that EclipseLink extends the java.util.Properties class with it's own NonSynchronizedProperties class.  

One methos getProperty(key, defaultValue) was not overridden properly.  On the SUN VM and the IBM VM on most OSs this didn't cause a problem as ultimately one of the methods that was overridden was called.

However, on the IBM VM on linux, the correct method is not called.
Fix:
    @Override
    public String getProperty(String key, String defaultValue) {
        String val = getProperty(key);
        return (val == null) ? defaultValue : val;
    }
