calc BeanShell script, save failure

[symptom] failure of BeanShell script (only 1 extra blank line)

Dear LO/AOO experts:

This symptom is found in 4 test environments. I wonder if this symptom could be reproduced in other platforms. I appreciate your guidance on where my mistake is.

The procedure to replicate the symptom is given below.

Thanks.

Ray
