ClassCastException when an unexpected pom file is found.

[turkeylurkey]

In my project there was a directory called "bin" that contained copies of files found elsewhere in the project. This included pom.xml files which the plugin detected as Liberty projects. When I clicked on the Liberty dashboard that pom was opened in the editor and this exception occurred.

java.lang.ClassCastException: class javax.swing.tree.DefaultMutableTreeNode cannot be cast to class io.openliberty.tools.intellij.LibertyModuleNode (javax.swing.tree.DefaultMutableTreeNode is in module java.desktop of loader 'bootstrap'; io.openliberty.tools.intellij.LibertyModuleNode is in unnamed module of loader com.intellij.ide.plugins.cl.PluginClassLoader @49807128)
