Description

CRITICAL since installing Modisco can break a non-Modisco aplication.

The Manifest editor clearly shows two warnings in /org.eclipse.modisco.utils.chart.metamodel/plugin.xml

a) the package should be ...metamodel.internal.chart.ChartPackage rather than ...metamodel.chart.chartPackage"

b) the genmodel should be model/chart.genmodel rather than model/birtChart.genmodel

The bad class spelling causes a ClassNotFoundException for any application that traverses the globalEPackage registry. Such applications should catch an exception per traversal entry, but many do not, so that their traversal terminates prematurely when Modisco's bad entry is traversed;the application either fails completely or only sees a partial EPackage registry.

As well as being very evident in the Manifest editor and problems view, this bug also causes Modisco tests to fail, so there is a lesser research query as to how this bug has escaped fixing.
