<p class="MsoNormal"> This is Tianmin Shi from the Amazon Corretto team. I am new to JDK development, please let me know if I missed anything.
<o:p></o:p></p>
<p class="MsoNormal"> I am working on backport <a href="https://bugs.openjdk.java.net/browse/JDK-7092821">
JDK-7092821</a> to 8u and 11u. however I think there is a potential race condition introduced by the change, which could cause method getService in class java.security.Provider to return incorrect results. Which is due to the read of legacyMap at line 1260
is not synchronized with clear and repopulate of the same map’s entries inside ensureLegacyParsed(), the fix is a simpler one liner in the attached webrev. Can we push this change to tip so I can backport it with
<a href="https://bugs.openjdk.java.net/browse/JDK-7092821">JDK-7092821</a> together?<o:p></o:p></p>
