Why a System bundled interface is not visible from a plug-in even it is explicitly imported? [Updated]

Hi,

My plug-in uses the following interface:

org.apache.jasper.runtime.JspSourceDependent

According to this Atlassian's instructions:

https://developer.atlassian.com/display/DOCS/Managing+Dependencies#ManagingDependencies-UsingContainer-providedPackages

I added the following dependency in the pom.xml:

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>jasper</artifactId>
    <version>6.0.20</version>
    <scope>provided</scope>
</dependency>

and imported full package for the latest version:

<instructions>
	<Import-Package>
		org.apache.jasper*;version="0.0.0",
		*;version="0.0.0";resolution:=optional

But I got a java.lang.NoClassDefFoundError!!

Any idea?

Thanks,

Pablo

This screenshot shows how while the org.apache.jasper package is exported from the System Bundle, it is DISABLED in the Import-Package section of the plug-in, even with the dependency and the import declared in the pom.xml.

Furthermore, the disabled package has "resolution: optional", but is explicitly declared. How is it possible???
