Odd classloader issue in tests with org.apache.xalan code.

[kklipsch]

This is an update for #869

In sbt 0.13.0 when using the built in java xslt transformer (javax.xml.transform.TransformerFactory) in a unit test (in this case using scalatest) you will get the following print to output "Warning: The encoding 'UTF-8' is not supported by the Java runtime.". Tracking this down, it appears that internally (in com.sun.org.apache.xml.internal.serializer.Encodings) the java transformer is looking for a properties file as a resource "com/sun/org/apache/xml/internal/serializer/Encodings.properties".

It finds this file correctly if run through a main in sbt but not in a unit test. This problem does not exist in 0.12.0.

class Xalan extends Suite {

    def testResource() {
        val factory = TransformerFactory.newInstance()
        val transformer = factory.newTransformer(xsltSource)

        transformer.transform(xmlSource, new StreamResult(nullOutputStream))
    }

    def xsltSource = stringToSource(xsltString)
    def xmlSource = stringToSource(xmlString)

    def nullOutputStream = new OutputStream {
        def write(b: Int) {}
    }

    private def stringToSource(string: String) =
        new StreamSource(new ByteArrayInputStream(string.getBytes(StandardCharsets.UTF_8)))

    private val xmlString = "<foo />"
    private val xsltString = "<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\" />"

}

I am guessing that this is now fixed with sbt/zinc#473. Please let us know if that's not the case.
