How to pass argument to class constructor when initialzed thru ::new in Java8

I am trying to use java stream instead of forloop
ids.stream().map(AccountPermissionsUpdate::new)
I have created an other constructor,
my question is: how to call the second constructor
new AccountPermissionsUpdate(id,true)
Thanks
public AccountPermissionsUpdate(long accountId) {
this.accountId = accountId;
}
public AccountPermissionsUpdate(long accountId, boolean forcedLogout) {
this.accountId = accountId;
this.forcedLogout = forcedLogout;
}

Just a side note (learned from Josh Bloch's book Effective Java), stream api is not a replacement for for loops, so be careful as it creates many stream instances in between. You can read more about that in his book though
