Description Andre Vanha 2004-05-07 00:08:55 UTC 
Using concat with the fixlastline option fails on an input boundary condition.

java.lang.ArrayIndexOutOfBoundsException: -1
        at org.apache.tools.ant.taskdefs.Concat$MultiReader.read(Concat.java:784
)
        at org.apache.tools.ant.taskdefs.Concat.concatenate(Concat.java:514)
        at org.apache.tools.ant.taskdefs.Concat.cat(Concat.java:463)
        at org.apache.tools.ant.taskdefs.Concat.execute(Concat.java:372)
        at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:269)

I haven't had a chance to see exactly what the boundary is, but adding an extra
line to one of the last input files read before the failure occurrs works around
the problem.

It would be a nice-to-have if the concat task displayed the path of processed
files at verbose or debug level.

Is is possible to get the files that caused
the problem?
Comment 2 peter reilly 2004-05-10 09:20:50 UTC 
Fixed in cvs,
Thanks for the report
Comment 3 Cameron Johnson 2006-09-05 16:02:25 UTC 
I am having the same problem with Apache Ant version 1.6.5 compiled on June 2 
2005.
Comment 4 Matt Benson 2006-09-05 16:06:04 UTC 
Please submit an example to evoke this undesirable behavior.  Thanks!
Comment 5 Cameron Johnson 2006-09-05 19:29:01 UTC 
Sorry I thought our build machine was using Ant version 1.6.5 but it actually 
was using 1.6.0  my mistake.
