> If some optional tasks that depend on an old version of ASM are installed, 
> patching fails with the following error: 
> {{/home/jpountz/src/lucene-solr/lucene/common-build.xml:565: 
> java.lang.IncompatibleClassChangeError: class 
> org.objectweb.asm.commons.ClassRemapper has interface 
> org.objectweb.asm.ClassVisitor as super class}}
> The reason is that ClassRemapper is loaded from the right place, but 
> ClassVisitor, its parent class, is loaded from the parent classpath which may 
> be a different version.
> It is easy to reproduce:
>  - download and extract ant-1.10.1 (latest version)
>  - run {{bin/ant -f fetch.xml -Ddest=system}}, this will add 
> {{lib/asm-2.2.3.jar}} among other files
>  - run {{ant clean test}} at the root of lucene-solr.
