[ https://issues.jboss.org/browse/JBIDE-7290?page=com.atlassian.jira.plugin... ] Denis Golovin edited comment on JBIDE-7290 at 3/8/11 9:05 PM: -------------------------------------------------------------- It is actually issue with org.eclipse.wst.server.core.internal.ServerPreferenceModifyListener which is listening to preferences changes and just tries to find /instance/org.eclipse.wst.server.core node in changed preference node lines 38-39. When it gets to the line 40 runtimes cannot be null because node method creates node if it cannot find it. Then it goes to the line 48 and tries to get preference 'runtimes' and sure gets empty string which DOM parser cannot parse. It reports an error in com.sun.org.apache.xerces.internal.util.DefaultErrorHandler at the line 95. {noformat} // Source of org.eclipse.wst.server.core.internal.ServerPreferenceModifyListener 28 public class ServerPreferenceModifyListener extends PreferenceModifyListener { 29 30 private static final String LOCKED_ATTRIBUTE_NAME = "locked"; //$NON-NLS-1$ 31 private static final String RUNTIMES_PREFERENCE_NAME = "runtimes"; //$NON-NLS-1$ 32 private static final String RUNTIME_NODE_NAME = "runtime"; //$NON-NLS-1$ 33 34 /* (non-Javadoc) 35 * @see org.eclipse.core.runtime.preferences.PreferenceModifyListener#preApply(org.eclipse.core.runtime.preferences.IEclipsePreferences) 36 */ 37 public IEclipsePreferences preApply(IEclipsePreferences node) { 38 Preferences instance = node.node(InstanceScope.SCOPE); 39 Preferences runtimes = instance.node(ServerPlugin.PLUGIN_ID); 40 if (runtimes != null) 41 removeLockedServerRuntimePreference(runtimes); //$NON-NLS-1$ 42 return super.preApply(node); 43 } 44 45 private void removeLockedServerRuntimePreference(Preferences preferences) { 46 try { 47 Document doc = DocumentBuilderFactory.newInstance() 48 .newDocumentBuilder().parse(new InputSource(new StringReader(preferences.get(RUNTIMES_PREFERENCE_NAME, "")))); //$NON-NLS-1$ 49 NodeList nodeList = doc.getElementsByTagName(RUNTIME_NODE_NAME); 50 for (int s = 0; s < nodeList.getLength(); s++) { 51 Node node = nodeList.item(s); 52 if (node.getNodeType() == Node.ELEMENT_NODE) { 53 NamedNodeMap attributes = node.getAttributes(); 54 Node locked = attributes.getNamedItem(LOCKED_ATTRIBUTE_NAME); 55 if (locked != null && Boolean.parseBoolean(locked.getNodeValue())) 56 node.getParentNode().removeChild(node); 57 } 58 } 59 StringWriter runtimes = new StringWriter(); 60 TransformerFactory.newInstance().newTransformer().transform(new DOMSource(doc), new StreamResult(runtimes)); 61 preferences.remove(RUNTIMES_PREFERENCE_NAME); 62 preferences.put(RUNTIMES_PREFERENCE_NAME, runtimes.toString()); 63 } catch (Exception e) { 64 //there is no defined runtime environment 65 return; 66 } 67 68 } 69 70 } {noformat} was (Author: dgolovin): It is actually issue with org.eclipse.wst.server.core.internal.ServerPreferenceModifyListener which is listening to preferences changes and just tries to find /instance/org.eclipse.wst.server.core node in changed preference node lines 38-39.
