Hi,
I have an application build on the Netbeans Platform that uses some netbeans
modules.
These netbeans modules import some subprojects (that are not Netbeans modules).
In one of the subproject, I need to call the
org.apache.configuration.Configuration (from "commons-configuration" Apache
project) class to check that a parameter is true (if it is, I display some
field on a HMI).
To set the Configuration install, I do it like this :
VariableSelectorGuiManager.setConfiguration(myInstance) ==> this is passed as
static.
Then, The VariableSelectorGui class gets the configuration instance an display
the fields depending on the parameters of the configuration instance.
The problem is the following :
- We have a standard Java HMI (not integrated in Netbeans) in which
everything works fine.
- With the Netbeans platform, the
"VariableSelectorGuiManager.setConfiguration(myInstance)" is done in the
register method of our "ModuleInstall" class. When we try to display the
VariableSelectorGui, this error is thrown :
java.lang.LinkageError: loader constraint violation: loader (instance of
org/netbeans/StandardModule$OneModuleClassLoader) previously initiated loading
for a different type with name "org/apache/commons/configuration/Configuration"

The error is thrown when trying to access a method of the Configuration
interface.
I already tried to add
"<publicPackage>org.apache.commons.configuration</publicPackage>" but it does
not work.
I also tried to add exclusions but it does not work too.
When I remove the code from the ModuleInstall>>register, the error is not
thrown.
All the modules/projects inherit from the same version of the
"commons-configuration" project.
Thanks,
Bastien
