Class files are closed and later used

The code is like this

// construct class view and hierarchy
        System.out.println("[+] building whole class view...");
        JavaView view = project.createFullView();
        Global.setView(view);
        ViewTypeHierarchy hierarchy = new ViewTypeHierarchy(view);
        Global.setHierarchy(hierarchy);

        view.getClasses().forEach(new Consumer<JavaSootClass>() {
            @Override
            public void accept(JavaSootClass javaSootClass) {
                if(javaSootClass.getType().getFullyQualifiedName().contains("RequestMapping")){
                    return;
                }
                if(javaSootClass.getType().getFullyQualifiedName().contains("AdminPlanningController")){
                    javaSootClass.getAnnotations(Optional.of(view));
                    return;
                }
            }
        });

When create full class view, it will call PathBasedAnalysisInputLocation.getClassSources(). In this method it will close zip filesystem

But when in getAnnotations method, it will reopen the zip filesystem and cause ClosedFileSyetem exeception.

I build call graph and it reports the same issue.
