Greetings, We have a (eXtra Large) fix for the following bug:
8167108 inconsistent handling of SR_lock can lead to crashes https://bugs.openjdk.java.net/browse/JDK-8167108 This fix adds a Safe Memory Reclamation (SMR) mechanism based on Hazard Pointers to manage JavaThread lifecycle. Here's a PDF for the internal wiki that we've been using to describe and track the work on this project: http://cr.openjdk.java.net/~dcubed/8167108-webrev/SMR_and_JavaThread_Lifecycle-JDK10-04.pdf Dan has noticed that the indenting is wrong in some of the code quotes in the PDF that are not present in the internal wiki. We don't have a solution for that problem yet. Here's the webrev for current JDK10 version of this fix: http://cr.openjdk.java.net/~dcubed/8167108-webrev/jdk10-04-full This fix has been run through many rounds of JPRT and Mach5 tier[2-5] testing, additional stress testing on Dan's Solaris X64 server, and additional testing on Erik and Robbin's machines. We welcome comments, suggestions and feedback. Daniel Daugherty Erik Osterlund Robbin Ehn
