>                 Key: JBTM-530
>                 URL: https://jira.jboss.org/jira/browse/JBTM-530
>             Project: JBoss Transaction Manager
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Transaction Core
>    Affects Versions: 4.5.0
>            Reporter: Davide Cavestro

> In JBossTM exceptions are often catched and left behind in favor of a new dedicated Exception (or Error) contextually thrown.
> This lead to a steady lack of information about the origin of the final symptom.
> As an example, see the following code snippet (extracted from com.arjuna.ats.internal.arjuna.objectstore.JDBCStore.JDBCStore())
> ...
> 		try
> 		{
> 			initialise("");
> 		}
> 		catch (Exception e)
> 		{
> 			throw new ObjectStoreError();
> 		}
> ...
> Here the original exception "e" is lost in favor of a new ObjectStoreError. No one will never know the cause of the thrown ObjectStoreError, nor see what's wrong without using a debugger (if ever available).
> Since I saw the binary distribution of JBossTM (at least version 4.5.0) is compiled for Java 1.5, I suppose you aren't denied to use the standard exception chaining mechanism introduced since Java 1.4 (namely the java.lang.Throwable.cause field)
> Please consider refactoring your code to chain the exception causes. It would be very useful.
