I am using Java 5 or Java 6.
The following test case fails 100%.

// Create an array of sources
final InputStream xsd = new FileInputStream("src/xml.xsd");
StreamSource[] sources = new StreamSource[1];
sources[0] = new StreamSource(xsd);
 
// Create the Schema Factory
final SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
[code]
// Create a schema
Schema schema1 = schemaFactory.newSchema(sources);
 
// Create a second schema, it will throw an Excepion
Schema schema2 = schemaFactory.newSchema(sources);

If you are creating a new array of sources before to create the second schema, it works fine. It seems that SchemaFactory.newSchema is making the passed sources as not "reusable"
I can't use new StreamSource(File) that is working. I need to work at the Stream level.
