Michael Hintenaus commented on WW-4333:
---------------------------------------
looking at the first part of the current regex
{code:java}
(.*\\.|^|.*|\\[('|\"))
{code}
the third opinion is .* which will match anything, so if this is intended the
regex could be simplified.
But I believe you wanted to match .*[... so the last pipe of the subregex would
be wrong.
I would suggest the following regex (removed pipe and use range instead of
group)
{code:java}
(.*\\.|^|.*\\[['\"])class(\\.|['\"]\\]|\\[).*
{code}
> ExcludedPatterns.CLASS_ACCESS_PATTERN is too restrictive
