<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">We did not understand the low priority of the issue (P4) as we see no way around the problem</span>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">We would greatly appreciate it if this fix could instead be backported to earlier LTS JDKs, ideally including JDK 17.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">Would someone be able to do this for us? We would be uncomfortable attempting to merge this ourselves.<o:p></o:p></span></p>
