Can't get replaceAll to match whenever tokens (^,\n,\b,$,etc) are used

Hoping someone may be able to help with this. I have been racking my brain with Atlassian's "rules" for how it was decided that replaceAll would be implemented.

Most of this seems to have been thrown right out the window.

Unfortunately, this didn't help me either.

Example follows

Issue Description:

Item

Notitem

Not an item
item

item

item
item
item

Intention: Remove all instances of "item" on a line by itself. The normal regular expression that would match what I want to remove is simply: ^item$

Failed attempts:

{{issue.description.replaceAll("(\nitem\b)","")}}

{{issue.description.replaceAll("(^item$)","")}}

{{issue.description.replaceAll("(\nitem$)","")}}

{{issue.description.replaceAll("(^item)","")}}

The valid string to accomplish my goal was:

{{issue.description.replaceAll("(?m)^item$\n?", "")}}

 Thank you me
