Hi,
We are migrating form 6i to 12c, it has one olb file for which 12c form builder crashing if we open this olb file or in this file in same path of source fmb.
1. 12c Form Builder crashes when olb file(one particular file) in same path, if we remove this olb file from path then form builder able to open
2. 12c Form Builder crashes when open olb file(one particulare file) in form builder 12c
We are able open this olb file in form6i without any issue.
Following steps has been done
1. Removed SENTRY_ENABLE & STANDARD CALENDAR
After this able to open olb file.
Not able to copy SENTRY_ENABLE & STANDARD CALENDAR to fmb file hence not able to identify issue of these objects.
How to identify issue related to this olb file?

Thanks in advance!
