For a record,
if I enable the xpathPerformance test (by removing @Ignore annotation)
and run "mvn install" with JDK 1.6,
using 1-argument version of XPathFactory.newInstance() results in printing
[[[
Running org.apache.taglibs.standard.tag.common.xml.ForEachTagTest
factory.getClass() = class org.apache.xpath.jaxp.XPathFactoryImpl
]]]
using 3-arguments version of XPathFactory.newInstance() results in printing
[[[
Running org.apache.taglibs.standard.tag.common.xml.ForEachTagTest
factory.getClass() = class com.sun.org.apache.xpath.internal.jaxp.XPathFactoryIm
pl
]]]
So there is a difference.
At the same time, in both cases the test does not complete after
running for 1 hour. I had to abort the tests and kill java process
forked by maven/junit. So here is no difference.
A comment for @Ignore is "Takes > 20s to run", so I was prepared to
wait, but an hour is more than I expected from that comment.
Maybe reducing the size of a sample document
("newBenchmarkDocument(200000)") will help.
This is not my priority for now. I just run it as I wanted to verify
whether my code change mattered.
