I am sorry for this mistake with answering to you and not to the group.
It was unintentional mistake. 


Ok, I will check ITS#7657.

Please try current RE24 code.  It is believed the fixes for ITS#8011 which are scheduled to be part of the 2.4.41 relase should resolve the issue.

Thanks,

I must wait for 2.4.41 release then. In the mean time I will use LTB project build with HDB to see can I have that version in working state for my colleagues test suite.
