Update dead link to grepcode

[aki-ks]

Grepcode is dead. openjdk.java.net should be more lasting.

That's strange. I've just changed a comment. How can this cause the build to fail?

Hi @aki-ks , I checked the build failure. I ran into the same issue in #438, which is a flaky test that occurs with a frequency of 1 / 1000 per build job (I believe there are ~10-15 build jobs per PR). The PR includes a fix in the second commit.

Due to the rarity of the flakiness, you can trigger a new build that should pass with a high probability of success. A build should be triggered when this PR detects a change in the source branch of the merge, which appears to be patch-1 of your repository.

I believe you can amend the the timestamp of the commit without changing the diff or the message and force push to your patch-1 branch. The following should work, but be sure that you are on the branch that has the desired change. :)

git commit --amend --no-edit
git push -f origin patch-1
