I've read an article about problems with the AElfred parser in the
ant-user list archive. AElfred comes with the XSLT processor Saxon.
The problem is that jakarta-ant/src/main/org/apache/tools/ant/ProjectHelper.java
uses the deprecated SAX1 API, which is not supported by AElfred.
The following patch modifies ProjectHelper.java so that a SAX2 XMLReader
and an XMLReaderAdapter are used if no SAX1 parser is available.
I've tested this patch with AElfred, Crimson and Xerces.
