             Summary: Exception access public method using Java extension
                 Key: XALANJ-2615

             Project: XalanJ2
          Issue Type: Bug

Using this sample stylesheet:

 
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform"
   xmlns:java="http://xml.apache.org/xalan/java">
 <template match="/">
  <!-- <variable name="p" select="java:exec(java:java.lang.Runtime.getRuntime(), 'cmd /c dir /b')"/> -->
  <variable name="p" select="java:exec(java:java.lang.Runtime.getRuntime(), 'cmd /c echo oui&amp;echo non')"/>
  <variable name="is" select="java:getInputStream($p)"/>
 </template>
</stylesheet>{code}
 

and this XML file

 
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<dummy/>{code}
 

When accessing the getInputStream method of the java.lang.Process class using XALAN I get this error:

This problem is due to the fact that the class ProcessImpl is not exactly identical to the interface java.lang.Process signature.  If you set the override to true in the method object (using AccessibleObject.setAccessible) you will be able to invoke the method.  This works in the JRE 8 xsl transformer.
