Michal Koscielny commented on NETBEANS-5251:
--------------------------------------------

I have the same error when opening js files. I don't know how much the content of a js file has impact on this error but it occurs even on very simple scripts. The error occurs only once (sometimes twice) after opening a project and the js file. If you want it to reproduce again it's necessary to restart Netbeans. I attach a simplest project to reproduce it: [^testproject.zip]. I'm using the latest build #251 from 20210113.

Here is the error:

{{java.lang.NullPointerException: The content parameter cannot be nulljava.lang.NullPointerException: The content parameter cannot be null at org.openide.util.Parameters.notNull(Parameters.java:64) at org.netbeans.modules.csl.api.Documentation.create(Documentation.java:52) at org.netbeans.modules.javascript2.nodejs.editor.NodeJsDataProvider.createProperty(NodeJsDataProvider.java:472) at org.netbeans.modules.javascript2.nodejs.editor.NodeJsDataProvider.addProperties(NodeJsDataProvider.java:484) at org.netbeans.modules.javascript2.nodejs.editor.NodeJsDataProvider.getGlobalObjects(NodeJsDataProvider.java:401) at org.netbeans.modules.javascript2.nodejs.editor.model.NodeJsModelInterceptor.getGlobalObjects(NodeJsModelInterceptor.java:47) at org.netbeans.modules.javascript2.nodejs.editor.model.NodeJsModelInterceptor.interceptGlobal(NodeJsModelInterceptor.java:41) at org.netbeans.modules.javascript2.model.ModelExtender.getExtendingGlobalObjects(ModelExtender.java:114) at org.netbeans.modules.javascript2.model.api.ModelUtils.getExtendingGlobalObjects(ModelUtils.java:1613) at org.netbeans.modules.javascript2.editor.hints.GlobalIsNotDefined.computeHints(GlobalIsNotDefined.java:80) at org.netbeans.modules.javascript2.editor.hints.JsHintsProvider.invokeHint(JsHintsProvider.java:275) at org.netbeans.modules.javascript2.editor.hints.JsHintsProvider.computeHints(JsHintsProvider.java:97) at org.netbeans.modules.csl.hints.infrastructure.HintsTask$1.run(HintsTask.java:114) at org.netbeans.modules.parsing.impl.TaskProcessor.callUserTask(TaskProcessor.java:586) at org.netbeans.modules.parsing.api.ParserManager$UserTaskAction.run(ParserManager.java:130) at org.netbeans.modules.parsing.api.ParserManager$UserTaskAction.run(ParserManager.java:114) at org.netbeans.modules.parsing.impl.TaskProcessor$2.call(TaskProcessor.java:181) at org.netbeans.modules.parsing.impl.TaskProcessor$2.call(TaskProcessor.java:178) at org.netbeans.modules.masterfs.filebasedfs.utils.FileChangedManager.priorityIO(FileChangedManager.java:153) at org.netbeans.modules.masterfs.providers.ProvidedExtensions.priorityIO(ProvidedExtensions.java:335) at org.netbeans.modules.parsing.nb.DataObjectEnvFactory.runPriorityIO(DataObjectEnvFactory.java:118) at org.netbeans.modules.parsing.impl.Utilities.runPriorityIO(Utilities.java:67) at org.netbeans.modules.parsing.impl.TaskProcessor.runUserTask(TaskProcessor.java:178)Caused: org.netbeans.modules.parsing.spi.ParseException at org.netbeans.modules.parsing.impl.TaskProcessor.runUserTask(TaskProcessor.java:186) at org.netbeans.modules.parsing.api.ParserManager.parse(ParserManager.java:81)[catch] at org.netbeans.modules.csl.hints.infrastructure.HintsTask.run(HintsTask.java:69) at org.netbeans.modules.csl.hints.infrastructure.HintsTask.run(HintsTask.java:52) at org.netbeans.modules.parsing.impl.TaskProcessor.callParserResultTask(TaskProcessor.java:561) at org.netbeans.modules.parsing.impl.TaskProcessor$RequestPerformer.run(TaskProcessor.java:786) at org.openide.util.lookup.Lookups.executeWith(Lookups.java:279) at org.netbeans.modules.parsing.impl.TaskProcessor$RequestPerformer.execute(TaskProcessor.java:702) at org.netbeans.modules.parsing.impl.TaskProcessor$CompilationJob.run(TaskProcessor.java:663) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418) at org.netbeans.modules.openide.util.GlobalLookup.execute(GlobalLookup.java:45) at org.openide.util.lookup.Lookups.executeWith(Lookups.java:278) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2033)}}

> # Installed NetBeans 12.2
>  # Started NetBeans
>  # Go to File -> Open File...
>  # Selected a js file to open
>  # Got a NullPointerException
>  
> Note:
> The file was somewhat big ~3MB. I did get the prompt about the file being too large and it could cause memory issues.
> Eventually the file opened and I was able to edit it but I did get the dialog about reporting the exception so I'm creating this issue with the information from the issue reporting dialog.
