| [lsp4e-dev] NullPointerException occurs during updating outline view |
| Hello lsp4e group: I use the latest version of lsp4e (org.eclipse.lsp4e_0.7.0.201807031601.jar) which is wonderful to integrate our own language server into Eclipse. Thank you very much. But I have encountered a problem that NullPointerException occurs during updating outline view under the condition that maxServerity > IMarker.SEVERITY_INFO. This is because calling Image res = LSPImages.imageFromSymbolKind(symbolInformation.getKind()); when the kind is object, and there is no image defined for this kind and return null. Kind regards, Bin The error log is as below: java.lang.NullPointerException at org.eclipse.jface.viewers.DecorationOverlayIcon.<init>(DecorationOverlayIcon.java:80) at
