------------------------------------
    Resolution: Fixed

Hi Șerban,  

  This is fixed on trunk and will ship in 2.0.1. The grammar and generated lexer now use a semantic
   predicate so **/ (and any number of asterisks before the closing slash) is handled correctly.
                                                                                                   
  I wanted to give you a heads-up on context. We just completed a significant cleanup of Axis2 —   
  removing 8 modules that were unmaintained or broken on current JDKs (Eclipse plugins, IDEA
  plugin, OSGi, JiBX, SOAPMonitor, Scripting, FastInfoset, WSDL 2.0). The CORBA module was         
  specifically retained because of your active usage.       

  That said, CORBA is in a similar position to the modules we removed — it requires an external ORB
   since CORBA was removed from the JDK in Java 11, and you are currently the only community member
   we hear from. That's not a problem today, but I want to be transparent: if the module has no    
  visible community activity over time, it will eventually be a candidate for removal in a future
  release.

  The best way to keep it healthy is exactly what you're doing — filing bugs, responding to issues,
   and contributing when you can. If there are others in your organization or community using the
  CORBA module, encouraging them to subscribe to the dev list or file issues would help demonstrate
   that the module has an audience worth maintaining.       

  Thanks for the report and for your patience on the fix.

> Axis2's IDL parser (Corba Module) gives fault on valid comment
> In our IDLs we have some comments with the following syntax:
> {code:java}
> /**
>  * some
>  * comment
>  * here
> **/{code}
> Of course, this is valid comment syntax, however it triggers parser errors:
> {code:java}

> After some analyzing, it seems that the parser does not accept multiple star symbols *"\*"* before the comment-terminating sequence *"\*/"* - so *"\*/"* is valid, but *"\*\*/"* is not.
> Note: We are using Axis2' Corba module to migrate our Corba services away from using Java Applets and towards web services. Even if this is not the intended use of Axis2, it seems to be the best open-source option for this type of migration.
