Fixed in branch petals-enterprise-3.1.x

The method JBIBootstrap.init(InstallationContext) must manage the installation context: are we in an installation context or in an uninstallation context. JBIBuilderDescriptor is not needed into an uninstallation context.

Two JBIBuilderDescriptors are used by a component:

  1. one by the bootstrap part,
  2. and one by the runtime part.

The JBIBuilderDescriptor of the runtime part can be easily fixed introducing a method close() to free static resources (set to null).
But the fix of the JBIBuilderDescriptor of the boostrap part is more difficult because the boostrap is initialized when unloading the component installer:
