Daan Creemers created TEIIDDES-2477: --------------------------------------- Summary: Nullpointer in WSConnectionInfoProvider.java when user is null Key: TEIIDDES-2477 URL: https://issues.jboss.org/browse/TEIIDDES-2477 Project: Teiid Designer Issue Type: Bug Components: Data Preview Affects Versions: 9.0, 8.6 Environment: Windows 7, JBoss Developer Studio 8.1.0, Teiid Designer 9.0.1.Final Reporter: Daan Creemers In the file https://github.com/Teiid-Designer/teiid-designer/blob/9.0.x/plugins/org.t... @line 101: if (null != user &! user.equals("")) { //$NON-NLS-1$ ... } It is not correctly captured that user can be null. No short-circuit operator is used and therefore, the right-hand side of the expression is evaluated which gives a NullPointer if user is null. After importing a REST Web Service to create a Source and View model, previewing the data generates the following NullPointer. java.lang.NullPointerException at org.teiid.designer.datatools.profiles.ws.WSConnectionInfoProvider.getTeiidRelatedProperties(WSConnectionInfoProvider.java:101) at org.teiid.designer.runtime.TeiidDataSourceFactory.createDataSource(TeiidDataSourceFactory.java:127) at org.teiid.designer.runtime.preview.PreviewManager.ensureConnectionInfoIsValid(PreviewManager.java:527) at org.teiid.designer.runtime.preview.PreviewManager.previewSetup(PreviewManager.java:1365) at org.teiid.designer.runtime.ui.preview.PreviewDataWorker$1.run(PreviewDataWorker.java:233) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:122) -- This message was sent by Atlassian JIRA (v6.3.11#6341)
