Error "Unable to create symbol table for :..." "java.lang.IllegalArgumentException: null"

[xpy...@googlemail.com]

Hi,

I get an error when analyzing a maven build with Sonar since an update to Java 8:

its the same error (same stack) as here (line 620): https://travis-ci.org/SonarSource/sonar-web/builds/164879018 

Do you have any idea, what causes this? I'm using Sonar 5.6.1 and Java Plugin 4.3.0.7717

Here is the stack from the jenkins build:

11:34:56 [ERROR] Unable to create symbol table for : D:\jenkins\workspace\Sonar_X4_XNSGTestProduct.4.0\XView.4.0\src\main\bc\de\aeb\xview\registry\XViewExtensionPoints.java

Hi, 

Just to be sure : your analysis is not failing, you just have this error in the log of the analysis  ?

This is an issue in the semantic analysis failing on a conditional expression : a ? b: c 

This should be happening in an assignement, so something like : myVar = a ? b : c ;

Would you be able to share the file XViewExtensionPoints.java ? (you can send it privately to me eventually) and if not, could you share the failing bit with relevant type information ? (there is something going on with generics here). 

Thanks.

Hi, 

looking at what is going on on the web plugin, it seems indeed related but not from the same cause as what seems involved in the case of web plugin is the following class and especially the field calling Array.asList : https://github.com/SonarSource/sonar-web/blob/master/sonar-web-plugin/src/main/java/org/sonar/plugins/web/lex/PageLexer.java

So I am deeply interested by the code of your file.

Cheers,

Hi,

your first tip was correct. It could not parse the = ? in the code below. After changing it to if else, it worked.

Thnx a lot

 

public synchronized <T extends FolderAC<?>, S extends ISheetAC> void registerSheet(Class<T> folderClass, Class<S> sheetClass, int sortOrder, ISheetLabelHandler<T, Class<S>> sheetLabelHandler, ISheetVisibleHandler<T> visibleHandler, String viewName) {

SheetRegistryEntry entry = new SheetRegistryEntry(sheetClass,viewName) ;

entry.visibleHandler = visibleHandler != null ? visibleHandler : new DefaultACSheetVisibleHandler();

entry.sheetLabelHandler = sheetLabelHandler != null ? sheetLabelHandler : new DefaultACSheetLabelHandler();

}
