Incorrect log results after merge [message #1743026]

Found a strange behavior (bug?) in a log command.

The corresponding test is attached.
It creates a repo, creates a branch, does some commits either to the created branch and to master, then merges master to the created branch. After merge it tries to calculate the number of commits between the branch and master. Because master has been already merged -- the branch is not behind the master, i.e. corresponding commit count should be 0. But 'Iterables.size' after a 'log' call returns the number of commits in the master minus 1.
Moreover, if 'sleep' in the line 43 is uncommented -- the bug will go away, and 'behind' is equal to 0.

What do I do wrong? Is it a bug in JGit library?

Wow, that's an amazing bug. With your test program I can reproduce it most of the times. I created bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=501211 . Let's continue discussion in bugzilla

Ciao
