Robert Munteanu commented on SLING-7432: ---------------------------------------- Interesting, I did not know about that. I looked briefly at the code and all that I found was the passing of 'inheritable' thread locals {code:java} if (inheritThreadLocals && parent.inheritableThreadLocals != null) this.inheritableThreadLocals = ThreadLocal.createInheritedMap(parent.inheritableThreadLocals); {code:java} Do you have any other references for the default thread locals? I'd like to make sure I don't mess anything up related to that. > Thread pool clean up code can lead to infinite loops in ThreadLocal.get > ----------------------------------------------------------------------- > > Key: SLING-7432 > URL: https://issues.apache.org/jira/browse/SLING-7432 > Project: Sling > Issue Type: Bug > Components: Commons > Affects Versions: Commons Threads 3.2.10 > Reporter: Robert Munteanu > Assignee: Robert Munteanu > Priority: Blocker > Fix For: Commons Threads 3.2.14 > > > The thread local clean up code added in SLING-6261 leads to Threads stuck in > {{ThreadLocal.get}}. > I am working on a simplified test case, but the stack trace is similar to > {noformat} > "pool-1-thread-1" prio=10 tid=0x00007f47f4374800 nid=0xb19 runnable > [0x00007f47e734e000] > java.lang.Thread.State: RUNNABLE > at java.lang.ThreadLocal$ThreadLocalMap.set(ThreadLocal.java:429) > at java.lang.ThreadLocal$ThreadLocalMap.access$100(ThreadLocal.java:261) > at java.lang.ThreadLocal.set(ThreadLocal.java:183) > at > org.apache.sling.commons.threads.impl.ThreadPoolExecutorCleaningThreadLocalsTest$RunnableImplementation.run(ThreadPoolExecutorCleaningThreadLocalsTest.java:100) > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) > at java.util.concurrent.FutureTask.run(FutureTask.java:262) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) > at java.lang.Thread.run(Thread.java:745) > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
