             Summary: Saxon plugin in locus causes runtime exceptions in Teiid Designer
                 Key: JBIDE-15248
                 URL: https://issues.jboss.org/browse/JBIDE-15248
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: locus
    Affects Versions: 4.1.0.CR1
            Reporter: Paul Richardson


Plugins dependent on the saxon-he plugin compile but error traces occur at runtime:

This is due to the revision (571) used to solve [JBIDE-15209|https://issues.jboss.org/browse/JBIDE-15209]. It would seem that just prior to an open source release, the saxon project updates saxon's edition.properties file to the following:

{code title=edition.properties}
config=net.sf.saxon.Configuration
platform=net.sf.saxon.java.JavaPlatform
{code}

This allows saxon to use open-source elements of its codebase rather than presumably defer to proprietary Saxonica code.
