We are experiencing [NPE when running Enso VSCode extension](https://github.com/enso-org/enso/pull/7054#issuecomment-2165921769): ``` Caused by: java.lang.NullPointerException: Cannot invoke "java.util.List.stream()" because the return value of "org.netbeans.spi.lsp.ErrorProvider.computeErrors(org.netbeans.spi.lsp.ErrorProvider$Context)" is null at org.netbeans.modules.java.lsp.server.protocol.TextDocumentServiceImpl.lambda$computeDiags$46(TextDocumentServiceImpl.java:2027) at java.base/java.util.stream.ReferencePipeline$7$1.accept(ReferencePipeline.java:273) ``` after some debugging I found that the [code in TextDocumentServiceImpl](https://github.com/apache/netbeans/blob/b332b296700219ecd1d6ee6255124f3486171af3/java/java.lsp.server/src/org/netbeans/modules/java/lsp/server/protocol/TextDocumentServiceImpl.java#L2004) added by Dušan [four months ago](https://github.com/apache/netbeans/commit/adde5d9277b71318e498d3c38a7d0de74a491bcd) and the code written by Sváťa [two years ago](https://github.com/apache/netbeans/blame/b332b296700219ecd1d6ee6255124f3486171af3/ide/spi.editor.hints/src/org/netbeans/modules/editor/hints/lsp/HintsDiagnosticsProvider.java#L53) disagree on whether a `null` is valid return type or not which leads to `NullPointerException`. This PR is fixing that by checking for `null` on the caller side. -- This is an automated message from the Apache Git Service.
