java.io.UTFDataFormatException while building BRMS package

Solution Verified - Updated -

Issue

When a rule has thousands of constraints like:

when
          $frame: Frame($code :
code, (code == '0004422' || code == '0006439' ||
code == '0027203' || code == '0027214' || code ==
'0132077' || code == '0174002' || code == '0182704' ||
code == '0235761' || code == '0274720' || code ==
'0287580' || code == '0287580' || code == '0316581' ||
code == '0341710' || code == '0341895' || code ==
'0341969' || code == '0342218' || code == '0343501' ||
code == '0345035' || code == '0408284' || code ==
'0408284' || code == '0412490' || code == '0413158' ||
code == '0454492' || code == '0454492' || code ==
'0487948' || code == '0540528' || code == '0540528' || ... 

... its package can not be built by BRMS:
