------------------------------------
Do you have a stack trace for this?
>From looking at the XStream src it appears that it should detect the best
>reflection provider... maybe its best guess bits are not happy?
> Depdendency on sun.* packages

> Key: GSHELL-81
> URL: https://issues.apache.org/jira/browse/GSHELL-81
> Project: GShell
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Core
> Reporter: Guillaume Nodet
> Assignee: Jason Dillon
> Fix For: 1.0-alpha-2
>
>
> It seems that GShell is currently unable to run without the sun.* packages in
> the classloader.
> The reason is that it uses xstream advanced mode which make use of these
> packages.
> If these packages are not on the classpath, xstream will default to the pure
> java reflection provider which will cause exceptions like the following:
> {noformat}
> Caused by: com.thoughtworks.xstream.converters.ConversionException: Cannot
> construct org.apache.geronimo.gshell.layout.model.CommandNode as it does not
> have a no-args constructor
> ---- Debugging information ----
> message : Cannot construct
> org.apache.geronimo.gshell.layout.model.CommandNode as it does not have a
> no-args constructor
> cause-exception :
> com.thoughtworks.xstream.converters.reflection.ObjectAccessException
> cause-message : Cannot construct
> org.apache.geronimo.gshell.layout.model.CommandNode as it does not have a
> no-args constructor
> class : org.apache.geronimo.gshell.layout.model.Layout
> required-type : org.apache.geronimo.gshell.layout.model.CommandNode
> path : /layout/nodes/command
> -------------------------------
> {noformat}
> I'm not sure if this is a good idea or if we should support that pure java
> mode...
