Cannot resolve method close() on javax.servlet.ServletOutputStream

Hello IntelliJ Community.

I'm using the latest build of IntelliJ IDEA: 11.1.2 #IU-117.418
I have a maven based Java project which contains the following code snippet in a JAX-RS resource class:

@javax.ws.rs.core.Context
javax.servlet.http.HttpServletResponse response;
...
javax.servlet.ServletOutputStream stream = response.getOutputStream();
stream.close();

The close method is highlighted red in my editor, with the error message stating: "cannot resolve method close()"; however building the project using Maven 2 (both from within IDEA and standalone from the command line) does not produce any errors / warnings about the close method. (in fact the application runs just fine, as expected)

Using ctrl+click and the "scroll to source button" I've discovered that IDEA believes the classes listed in the code snippet above resolve to the following jars:

javax.ws.rs.core.Context [Maven: com.sun.jersey:jersey-core:1.6]
javax.servlet.http.HttpServletResponse [Maven: com.google.gwt:gwt-user:2.4.0]
javax.servlet.ServletOutputStream [Maven: com.google.gwt:gwt-user:2.4.0]

But there may be some confusion between what IntelliJ believes the resolution is and what the resolution actually is when Maven builds the my pom since ctrl+N ServletOutputStream produces the following list:

ServletOutputStream (javax.servlet) Maven: com.google.gwt:gwt-user:2.4.0
ServletOutputStream (javax.servlet) Maven: org.glassfish:javax.servlet:3.0
ServletOutputStream (javax.servlet) Maven: javax.servlet:servlet-api:2.5

<dependency>
     <groupId>com.sun.jersey</groupId>
     <artifactId>jersey-server</artifactId>
     <version>1.6</version>
</dependency>

<dependency>
     <groupId>com.google.gwt</groupId>
     <artifactId>gwt-user</artifactId>
     <version>2.4.0</version>
     <scope>provided</scope>
</dependency>
<dependency>

     <groupId>com.sun.jersey</groupId>
      <artifactId>jersey-grizzly2</artifactId>
      <version>1.6</version>
      <scope>test</scope>
 </dependency>

Can you see what I'm missing? Is this an IntelliJ Maven bug or have I configured something incorrectly? Any help is greatly appreciated!

P.S. I've attempted to invalidate the caches and reimport maven projects, neither action had any affect on the unresolved method.
