This is the tool behind SignatureTest infrastructure. It checks for incompatibilities and is currently done by NetBeans' own version of an OpenJDK sigtest tool tool. This adds a standard Ant task to check for binary backward compatibility, mutual signature compatibility. The binary compatibility check ignores generic types. Its sources are distributed together with its Mercurial repository and are available under GPL version 2.
Binary Builds are available from our hudson builder. Get the sources with
hg clone http://hg.netbeans.org/apitest/ cd apitest ant jar test # open in NetBeans
