After investigating, I found that this bug is a side effect of [SKARA-1807](https://bugs.openjdk.org/browse/SKARA-1807). In SKARA-1807, we escaped the issue title in PR body and the title of JDK-8303474 includes ‘>’. So the csr issue title in the pr body is `(fc) FileChannel::transferFrom should support position > size()`. In some logic, the csr bot is looking for the title of the csr issue(not escaped), so the bot is looking for `(fc) FileChannel::transferFrom should support position > size()` and if the bot couldn’t find the csr issue title, the bot would assume this pr body is outdated and will update it. Therefore, the bot is stuck in an infinite loop.
