Method EclipseJavaUtil.resolveType returns invalid cached values
----------------------------------------------------------------

                 Key: JBIDE-9645
                 URL: https://issues.jboss.org/browse/JBIDE-9645
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: CDI, common/jst/core
    Affects Versions: 3.3.0.M2
            Reporter: Viacheslav Kabanovich
            Assignee: Viacheslav Kabanovich
             Fix For: 3.3.0.M4


EXECUTE: Create beans in cdi project
{code}
public class A {
	@Inject B.D a;
}

public class B extends C {
	
}

public class C {
	public static class D {}
}
{code}
ASSERT: Injection point is resolved to C.D - check by open-on.
EXECUTE: copy declaration of class D into class B and wait for the incremental build.
FAILURE: Injection point is still resolved to C.D
EXECUTE: Touch class A by an insignificant modification and wait for the incremental build.
ASSERT: Injection point is resolved to B.D

This case is not very actual, but reveals the problem in the simplest way. More actual use case - editing classpath so that a type referenced by a Java source changes resolution.

Cache is cleaned for a modified file. There is no simple logic in cleaning cache for all types that may be affected by a modification, and a thorough check may take so much time that cache will be of no use. I see only one safe solution - to clean cache before each build.
