If the timer event runs in the same thread as your current call to
checksynchro resides then it will work. If it's executed by a different
thread then not.

Yep, yep, yep some very good news...
1) Added a new procedure in fpc library:
=>
procedure uos_checksynchro(PEnv: PJNIEnv; Obj: JObject) ; cdecl;
begin
checksynchronize();
end;
2) And, of course, in fpc library exported as:
=>
exports
...
uos_checksynchro name 'Java_uos_checksynchro',

No.

I use then queue() or synchronize() inside the thread to execute that
