A project demonstrating the problem.

Seems that the depend task does not handle classfiles with the invokeDynamic properly:
/tmp/invokeDynamicByteCode/nbproject/build-impl.xml:923: The following error occurred while executing this line:

This may exist for some time, but is a bigger problem now, as it seems that recent JDK-lambda builds appear to be using invokeDynamic to implement lambdas.

To reproduce:
-download and unpack the attached project
-run "ant" inside the project - the above exception appears for me

The above steps work even when running on JDK6, but the project as such can only be succesfully compiled on a lambda JDK.

Tested with custom build ant from revision 1404889, and with:
$ ant -version
Apache Ant(TM) version 1.8.2 compiled on December 20 2010

https://github.com/jenkinsci/constant-pool-scanner/issues/2 is similar.
Comment 2 Antoine Levy-Lambert 2013-01-22 05:06:15 UTC 
can you build ant from the latest sources in svn found under http://svn.apache.org/repos/asf/ant/core/trunk/ and try your build?
