javax/xml/jaxp/module/ServiceProviderTest/BasicModularXMLParserTest.java
 javax/xml/jaxp/module/ServiceProviderTest/LayerModularXMLParserTest.java

 Fails if jdk/lib/stax.properties exist. This file seems created and left over by
 javax/xml/jaxp/unittest/stream/FactoryFindTest.java:

     @Test
     public void testFactoryFindUsingStaxProperties() {
 ...
         String configFile = System.getProperty("java.home") + File.separator + "lib" + File.separator + "stax.properties";

         File f = new File(configFile);
         if (f.exists()) {
             try {
                 FileInputStream fis = new FileInputStream(f);
                 props.load(fis);
                 fis.close();
             } catch (FileNotFoundException e) {
                 return;
             } catch (IOException e) {
                 return;
             }
         } else {
             props.setProperty(FACTORY_KEY, "com.sun.xml.internal.stream.XMLInputFactoryImpl");
             try {
                 FileOutputStream fos = new FileOutputStream(f);
                 props.store(fos, null);
                 fos.close();
                 f.deleteOnExit();
             } catch (FileNotFoundException e) {
                 return;
             } catch (IOException e) {
                 return;
             }
         }

 In case FactoryFindTest.java failed to delete it's created file jdk/lib/stax.properties, BasicModularXMLParserTest.java and LayerModularXMLParserTest.java then will fail:

 Expect javax.xml.stream.XMLInputFactory is provided by module xmlprovider1, but actual implementation class com.sun.xml.internal.stream.XMLInputFactoryImpl is provided by module java.xml
 Exception in thread "main" java.lang.AssertionError: 1 services are not provided by expected module
 at Main.main(Main.java:63)

 test BasicModularXMLParserTest.testWithTwoProvider(): failure



 Need to move FactoryFindTest.java to isolatedjdk to fix this issue.
