"Find References" doesn't show the reference in .class files

[mickaelistria]

Let's make sure issue is not already fixed in snapshots first.

• [x] I verified I can reproduce this issue against latest snapshots build

Steps to reproduce

From a fresh installation and clean workspace:

• Create a java project with a dummy java file
• Make this file reference some JDK type (eg FileInputStream)

I tried

• Select a location in FileInputStream token in the file
• Find References

I expected: Several references in the JDK code

But got: nothing

Here is some relevant log output form (<workspace>/.metadata/.log)

The JDT communication log can show many entries with URIs of form jdt://contents/jdk.compiler/com.sun.tools.javac.api/JavacTrees.class. Those URIs don't seem to show in the result list.

• [x] I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.
