>
> when running several pig scripts one after another using java class 
> PigServer, the classpath in taskjvm.sh gets longer and longer, eventually 
> execution breaks on having a too long classpath. 
> The jar registered at the pig script are appended to the classpath on every 
> execution. It seems that PigContext's skipJars member is the root cause for 
> this as it is added jars that already exists in the list multiple times.
