class com.google.common.collect.StandardTable$RowMap cannot access its superclass com.google.common.collect.Maps$ImprovedAbstractMap

[GoogleCodeExporter]

Using:
* Sun JDK 1.6.0_20
* Hudson 1.384
* Hudson Maven Plug-in 1.54

When I call this piece of code within a Hudson plug-in:

Table<String, String, String> index = TreeBasedTable.create();
...
for (String key : index.rowKeySet()) {
   ...
}

I get the following exception on ''index.rowKeySet()'':

java.lang.IllegalAccessError: class 
com.google.common.collect.StandardTable$RowMap cannot access its superclass 
com.google.common.collect.Maps$ImprovedAbstractMap

(I have attached the complete stack trace in attachment).

When I run it in a standalone program, I get no problem.

I seems that somehow the Hudson Plug-in class loader cannot deal with the link 
between the two classes and I was wondering if it could be simplified (by 
changing the modifiers of the classes or creating them a top-level, and 
changing their scope into non-public).

Regards,
Damien.

Actually, I think that replacing the following line in ''Maps'':

abstract static class ImprovedAbstractMap<K, V> extends AbstractMap<K, V> {

by:

public abstract static class ImprovedAbstractMap<K, V> extends AbstractMap<K, 
V> {

should do the trick. I will test locally.

No, there is a conflict between the version of Guava I request (r09) and the 
version of Guava Hudson is packaged with (r06)...

Indeed, Hudson is using Guava r06... So I will have to downgrade my plug-in to 
r06...

This issue can be closed.
