Increase in Metaspace with TransformerFactory's XSLT Transformer

When I run the following code with multiple different requests, the java metaspace is getting increased. 

        public String applyXsltOnXml(String xmlString, String xsltInput) throws TransformerException {
         String result = null;
         try (StringReader stringReader = new StringReader(xmlString);
                 StringWriter writer = new StringWriter()) {
             TransformerFactory factory = TransformerFactory.newInstance();
             Transformer transformer = factory.newTransformer(new StreamSource(new StringReader(xsltInput)));
             transformer.transform(new StreamSource(stringReader), new StreamResult(writer));
             result = writer.toString();
         } 
         return result;
     }

Could you please explain what is happening behind the scenes ? why the java metaspace is getting increased ?

Xalan generates bytecode and I imagine that's what's occupying the metaspace.
