ecj javac target/source build.xml rewriting

Howdy,

I'm looking at http://bugs.gentoo.org/show_bug.cgi?id=196080

Basically what is happening is that these lines in build.xml
are not being rewritten with the correct version:

  <property name="javac.target" value="1.2"/>
  <property name="javac.source" value="1.2"/>

Ideally these should be:

  <property name="javac.target" value="$JAVA_PKG_WANT_TARGET"/>
  <property name="javac.source" value="$JAVA_PKG_WANT_SOURCE"/>

While [email protected] has created a patch to bump these
values to 1.3, this just postpones the real problem.

Digging into java-ant-2.eclass I think that java-ant_bsfix_files()
is the method that is modifying build.xml.  The problem seems
to be that the xml-rewrite*.py scripts are designed to only
match element name (e) plus attribute (a) to change new value (v):

  <e a=v>

I don't see how to specify element name (eM) plus an attribute
(aM) with value (vM) to match plus attribute (a) to change to
new value (v):

  <eM aM=vM a=v>

Does anyone have any ideas of how this could be done?


TIA,
Roy
