[Classpathx-xml] a patch to javax/xml/transform/stream/StreamSource.java

[Ito Kazumitsu]

javax/xml/transform/stream/StreamResult.java says:

|       public void setSystemId(File file) {
|           try {
|               this.systemId = StreamSource.fileToURL (file).toString ();
|           } catch (IOException e) {
|               // can't happen
|               throw new RuntimeException (e.getMessage ());
|           }
|       }

But an IOException can happen when the file does not exist,
which is usually a case when we try to make a new output
file using Saxon XSLT processor.

|bash$ SaxonDir=/home/ito/xml/java/saxon
|bash$ UserDir=/home/ito/javalib/saxon
|bash$ GNUJAXP=/home/ito/xml/java/gnu/gnujaxp.jar
|bash$ CLASSPATH="$CLASSPATH;$GNUJAXP;$UserDir;$SaxonDir/saxon.jar;." export 
CLASSPATH

The following patch to javax/xml/transform/stream/StreamSource.java
helps solve this problem.
