>             Project: UIMA
>          Issue Type: Bug
>          Components: Core Java Framework
>    Affects Versions: 3.0.0SDK-alpha02

>
> The log4j (v2) API has calls which allow both a message (with substitutable parts) and arguments to substitute.
> It also has calls which allow passing a throwable.
> The calls that support passing a throwable do not support substituable parts.  The bridge code assumed that it did.  This resulted in an array of args being treated as one substitutable value. 
>  
> Change the bridge code to call one of two different log4j methods, depending on whether or not a throwable is being included.
