[izpack-devel] fix: PathInputPanel

[Stefan Wachter]

Hi all,

the current version of PathInputPanel logs a stacktrace on Linux systems when no defaultInstallDir 
is specified and no TargetPanel.dir.x resource is present.


There are two problems:

1. The resouce "TargetPanel.dir.unix" is tried to access twice. The first time the access is not 
surrounded by a try-catch block.

2. It is possible that no suitable resource is found. In that case no InputStreamReader can be 
instantiated.

Attached you find a corresonding patch.

Cheers,
--Stefan


PS: The problem is also present in older versions of IzPack. But now the stack trace is printed 
because the following lines where added to the loadDefaultInstallDir() method:

             //mar: what's the common way to log an exception ?
             e.printStackTrace();
