FileNotFoundException for PatternLanguage.genmodel #215

Closed bergmanngabor closed 12 years ago

bergmanngabor commented 12 years ago

Caught and logged. Seems harmless. Also occurs with EMFPatternLanguage.genmodel.

How to reproduce: no clue, but happens often.

The source of the exception is the registered genmodel in the plugin.xml of the org.eclipse.viatra2.patternlanguage.core project stating:

  <extension point="org.eclipse.emf.ecore.generated_package">
    <package 
       uri = "http://www.eclipse.org/viatra2/patternlanguage/core/PatternLanguage" 
       class = "org.eclipse.viatra2.patternlanguage.core.patternLanguage.PatternLanguagePackage"
       genModel = "org/eclipse/viatra2/patternlanguage/core/PatternLanguage.genmodel" /> 

  </extension>

In other words, the issue shows that the non-absolute URI values described in the extensions are handled incorrectly.
