Two cobertura questions

Hello everybody.
I would like to use Cobertura to measure the coverage of a JUnit testsuite. However I found two problems: 1. When instrumenting the code I get a lot of "WARN visitEnd, No line number information found for ... Perhaps you need to compile with debug=true?" type of warnings. The code is compiled with debug=true. I also found this blogpost (http://meera-subbarao.blogspot.com/2008/07/cobertura-instrument-warn-visitend-no.html) and putdebuglevel="vars,lines,source" in my build task, but it made no difference. What seems weird to me, is the fact that every warning seems to be related to an anonymous inner class... Does the instrumentation code have problems with anonymous inner classes or am I doing something wrong? 2. When I tried to generate the report, I got the following exception: Cobertura 1.9.3 - GNU GPL License (NO WARRANTY) - See COPYRIGHT file Cobertura: Loaded information on 2338 classes. net.sourceforge.cobertura.javancss.parser.ParseException: Encountered " ":" ": "" at line 1322, column 31.

At the indicated line in the source there is a code like this: for (Foo i : bar) { ... } Does the exception mean that the parser employed by cobertura doesn't support this construct? If this is the case, is is possible to generate a report without parsing the source code? I'm interested only the line numbers anyway and I'll use some custom code to generate the reports. I'm using a rather old JDK (1.5.0_14) because this is a legacy codebase. I'll try to update to the latest JDK 5.0 (.21) later today and see if it makes a difference.

I'm using version 1.9.3, which seems to be the latest available from the site. I will try to build from source later today.
