[Cobertura-devel] Unable to get lock cobertura.ser

[Mikael P. <mik...@er...>]

Hi,
 
I get the following problem when executing tests ( <junit>) in ant 1.7
using cobertura 1.9.2.
Any ideas why?

This is known to happen on Linux kernel 2.6.20.
Make sure cobertura.jar is in the root classpath of the jvm 
process running the instrumented code.  If the instrumented code 
is running in a web server, this means cobertura.jar should be in 
the web server's lib directory.
Don't put multiple copies of cobertura.jar in different WEB-INF/lib
directories.
Only one classloader should load cobertura.  It should be the root
classloader.
