Hello,
this is going to be nearly the same as restructuring the build process, since
we have more then one component, using these targets. I am currently digging
deeper into this, and hope, that I can restructure the build tonight. This is
going to get a long night :-(
If you can recompile Ant, (1.6.5) there is a memory leakage associated
with <antcall> and <taskdef> that can be fixed easily.
In IntrospectionHelper.java, the method
public static synchronized IntrospectionHelper getHelper(Class c) {
IntrospectionHelper ih = (IntrospectionHelper) helpers.get(c);
if (ih == null) {
ih = new IntrospectionHelper(c);
helpers.put(c, ih);
}
return ih;
}
Change this to:
public static synchronized IntrospectionHelper getHelper(Class c) {
IntrospectionHelper ih = (IntrospectionHelper) helpers.get(c.getName());
if (ih == null || c != ih.bean) {
ih = new IntrospectionHelper(c);
helpers.put(c.getName(), ih);
}
return ih;
}
Recompile (./build.sh or build.bat in the source), copy
$ant_source/dist/lib/ant.jar
to $ANT_HOME/lib (*not* the other jar files as they need third party jars
to compile).
This change is in the svn version of ant, but was done after
the release of ant 1.7.0beta3.
