How to revoke some permission from user in a space through java

neetubhatt

I want to revoke some permission from a user in a space but not able to find a way that works .

1. when iam trying with removeallpermission then all the access of user is revoked , sometime the user is deleted from his own space .

2)I have tried 

SpacePermission spacePermission = SpacePermission.createUserSpacePermission(SpacePermission.EXPORT_SPACE_PERMISSION,space,user);
spacePermissionManager.removePermission(spacePermission); 

but this is also not working and making no change in permissions.

List<SpacePermission>permissionsVal= space.getPermissions();
for(SpacePermission permission:permissionsVal){
if( permission.isUserPermission()){
User user= permission.getUserSubject();
if(permission.getType()=="EXPORTSPACE")
{
permissionsToRemove.add(permission);
}}}

I have tried it this way and its working fine to remove permission for user from a space .
