Can't seem to get rid of 1.6

I have set JAVA_HOME to a 1.5 java home.

I have traced the mvn shell script to watch it get used.

I have set <source/> and <target/> in the compiler plugin to 1.5. I
have checked the results with help:effective-pom.

Nonetheless, code that calls the new
DocumentBuilderFactory.newInstance(<several args>) compiles and even
runs with no errors.

I can't easily deinstall 1.6 from my mac. Has anyone else got a
suggestion what stupid mistake I'm making here?

My understanding is the by using that target attribute, maven is still using the default java installation to compile, but the byte code generated will be compatible with the java version specified.

A bit more detail from sh -x on the mvn command ... 1.5 goes in, 1.6 comes out.

That doesn't help with bootclasspath inventory.

However, I've found my problem. On MacOS snow leopard, the So-called
Java 1.5 home is actually java 1.6!

I was just about to ask that, if the 1.5 home was symlinked to 1.6.

You may want to consider the animal-sniffer plugin to detect and error
on Java API incompatibles.  The one from Codehaus mojos should be out
shortly, in the mean time Kohsuke's is working for me.
