This should probably be a FAQ because finding the information is not obvious
at all.  Yes it's possible both with JAXP and separately.  The simplest way
if you have the opportunity to edit your code is just give the class name
explicitly to SAXBuilder.

SAXBuilder builder = new
SAXBuilder("org.apache.crimson.parser.XMLReaderImpl", false);

Or you can not specify a class in the constructor, have JAXP in your
classpath and put this on your command line

java
-Djavax.xml.parsers.SAXParserFactory=org.apache.crimson.jaxp.SAXParserFactor
yImpl yourclass

the default parser is determined by the static class method
javax.xml.parsers.SAXParserFactory.newInstance() and which one is returned
depends on who wrote the SAXParserFactory class and which one is first in
the classpath.

I believe thats the original Crimson parser before it was given to Apache,
