Example 81 with XMLStreamReader

use of javax.xml.stream.XMLStreamReader in project webservices-axiom by apache.

the class TestIOExceptionInGetText method runTest.

@Override
protected void runTest() throws Throwable {
    // Construct a stream that will throw an exception in the middle of a text node.
    // We need to create a very large document, because some parsers (such as some
    // versions of XLXP) have a large input buffer and would throw an exception already
    // when the XMLStreamReader is created.
    StringBuffer xml = new StringBuffer("<root>");
    for (int i = 0; i < 100000; i++) {
        xml.append('x');
    }
    InputStream in = new ExceptionInputStream(new ByteArrayInputStream(xml.toString().getBytes("ASCII")));
    XMLStreamReader originalReader = StAXUtils.createXMLStreamReader(in);
    InvocationCounter invocationCounter = new InvocationCounter();
