The Eclipse compiler can't resolve java.lang.annotation.Annotation from source any more.

Since bug 419331, I get a compile error "The type java.lang.annotation.Annotation cannot be resolved. It is indirectly referenced from required .class files" when I try to compile the attached project. When I revert the change for that bug, then the Annotation type is found, and I get better (expected/solvable) problems. (The given project is very incomplete but shows the issue).

Background: I'm trying to regenerate rtstubs18.jar for the JDT/UI tests, so that it includes the APIs from latest JREs. We need this e.g. for the test case in bug 425183 comment 10.

ECJ should generally be able to compile a complete rt.jar from source.

Hmm, we are not hitting this problem in https://bugs.eclipse.org/bugs/show_bug.cgi?id=427787, unless 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=428307 has something to with this.

Stephan, something to bear in mind.

Apparently happens only on ECJ runs without JRE - In the IDE we are building with
rt.jar in the build path with class path order ensuring that sources get
picked up first - that could explain it.

Thanks Markus,

Fix and test released here:

http://git.eclipse.org/c/jdt/eclipse.jdt.core.git/commit/?h=BETA_JAVA8&id=78bbbeed8347e023a39893a354552d3196a82094

Basically I mended the original fix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=419331 to not
overeagerly try to resolve jlaA.

Thanks. Verified in BETA_JAVA8 that the project from comment 0 doesn't stop with that error any more, and that I can compile the full rtstubs18.jar again.
