Description Jouk Jansen CLA 2012-01-05 03:21:11 EST 
Build Identifier: 1.2.0.201112221803-r

On an OpenVMS 8.4 (IA64) on which JAVA 1.6.0-3.p1 is installed I get the following error when I try the merge command of jgit:

bolero-jj) jgit version
jgit version 1.2.0.201112221803-r
bolero-jj) jgit fetch

Comment 1 Kevin Sawicki CLA 2012-01-05 15:46:00 EST 
Does a index.lock file exist in the /$disk6/JOUKJ/git/jed/jed/.git directory?
Comment 2 Jouk Jansen CLA 2012-01-06 03:39:13 EST 
Yes, index does exist

Note that file access on an OpenVMS system is quite different from i.e. linux:
If you open a file, by default it is locked for all other use, except when you explicitly open it as "shared". My guess is that the file is already in use by some other instance of jgit.
Comment 3 Jouk Jansen CLA 2012-01-06 05:22:19 EST 
I deleted the index.lock file manually.
After that the merge command worked.

the index.lock file was created when I did the original "clone" of the repository.
Comment 4 Matthias Sohn CLA 2012-06-14 08:31:23 EDT 
can we close this bug ?
Comment 5 Jouk Jansen CLA 2012-06-18 03:47:12 EDT 
Still the only work-around is deleting the index.lock manually. 
Is this going to be solved?
