Bug 79174 organize imports bug in 3.1m2
when organizing imports in class implementing Map<K,V>, can't seem to get rid of "import java.util.Map.Entry" using ctrl-shift-o, yet it still complains that its not needed. so i deleted it manually and it stopped complaining.
org.eclipse.jdt.ui.tests/ui/org/eclipse/jdt/ui/tests/core/ImportOrganizeTest.java
IPackageFragment pack1= sourceFolder.createPackageFragment("pack1", false, null);
		StringBuffer buf= new StringBuffer();
		buf.append("package pack1;\n");
		buf.append("\n");
		buf.append(body.toString());
		
		ICompilationUnit cu= pack1.createCompilationUnit("C.java", buf.toString(), false, null);
		IChooseImportQuery query= createQuery("C", new String[] {}, new int[] {});
		OrganizeImportsOperation op= new OrganizeImportsOperation(cu, order, 99, false, true, true, query);
		op.run(null);
		buf= new StringBuffer();
		buf.append("package pack1;\n");
		buf.append("\n");		
		buf.append("import org.eclipse.jdt.internal.compiler.classfmt.ClassFileReader;\n");
		buf.append("import org.eclipse.jdt.internal.compiler.env.NameEnvironmentAnswer;\n");
		buf.append("\n");
		buf.append("import org.eclipse.core.resources.IContainer;\n");
		buf.append("import org.eclipse.core.resources.IResource;\n");
		buf.append("import org.eclipse.core.runtime.CoreException;\n");
		buf.append("import org.eclipse.core.runtime.IPath;\n");
		buf.append("\n");
		buf.append(body.toString());
		
		assertEqualString(cu.getSource(), buf.toString());
