execute bit set for "group" and "other"?

I've noticed that files (scripts) that I have imported via the CLI (on Linux) into RTC with the execute bit set for owner, group and other (i.e. with initial permissions of 755), seem to lose that execute bit for the group and other, regardless of my umask.

Ex. Here is the file that was "shared"... (I ran scm share)

rtp-spvtg-lnx1:294> ls -l get*
-rwxr-xr-x 1 dmarsico eng 404 Apr 27 14:38 getmac.sh

# here is the property for it...
scm property get jazz.executable getmac.sh
.../getmac.sh
jazz.executable - true

# here is when I did a "scm load"
with a umask 0

-rwxr--r-- 1 dmarsico eng 404 May 6 08:14 getmac.sh


Is this expected or am I doing something wrong?

Thx

Dave
