But, it doesn't escape these characters if they are found inside the pattern value.</p> <p>Due to this issue, attempts to use PatternConstraint::getRegularExpression as is with Java Pattern/Matcher classes doesn't work as expected.</p> <p>Operating System: All<br/> Platform: All</p> YANGTOOLS-658

Escape Meta-characters like $, ^ in Regular Expression provided in pattern statement

I couldn't find the relevant code change that could have solved this issue.<br/> 2. Apparently, the issue is not fixed. I had a work-around in my code for this issue. Even after upgrade to boron, removing the wor-around is causing the original issue.<br/> 3.
