HELP: Google calendar API for java

Hello,
I'm sad. I have almost done whole synch application for google calendar. But I 
need your help with bug.
I don't use default calendar, I have created specific Evernote calendar, and 
events are created inside this calendar. Reading of events, insertion of events 
are not problem. The updating, or deleting events cause: 

Exception in thread "main" com.google.gdata.util.ServiceException: Internal 
Server Error
Service error: could not update entry

    at com.google.gdata.client.http.HttpGDataRequest.handleErrorResponse(HttpGDataRequest.java:624)
    at com.google.gdata.client.http.GoogleGDataRequest.handleErrorResponse(GoogleGDataRequest.java:563)
    at com.google.gdata.client.http.HttpGDataRequest.checkResponse(HttpGDataRequest.java:552)
    at com.google.gdata.client.http.HttpGDataRequest.execute(HttpGDataRequest.java:530)
    at com.google.gdata.client.http.GoogleGDataRequest.execute(GoogleGDataRequest.java:535)
    at com.google.gdata.client.Service.update(Service.java:1563)
    at com.google.gdata.client.Service.update(Service.java:1530)
    at com.google.gdata.client.GoogleService.update(GoogleService.java:583)

BUT only sometimes! It means from 3 time - 2 times cause this exception, and 3 
is ok. It seems that the service has some wrong implemented threads processes.

I try use update() on entry, delete() on entry. Or by documentation:

    URL editUrl = new URL(event.getEditLink().getHref());
    CalendarEventEntry updatedEntry = calendarService.update(editUrl, event);

But all is same. Still internal error. Can you help me? If you want to provide 
some more information, I will help you. I need to finish my application, and 
this is critical error of main processes.

For approach to specific calendar I use url from your forums:

http://www.googe.com/feeds/calendar/{CALENDAR_ID}/private/full

I wrote that listing, and inserting are not problem. The updating, and deleting.

Thanks for help...
