🍒 11111 - Preload scope classes to prevent virtual thread deadlock by PerfectSlayer · Pull Request #11131 · DataDog/dd-trace-java

PerfectSlayer · 2026-04-16T10:00:37Z

Backport #11111 to release/v1.61.x

(cherry picked from commit e95e91e)

…deadlock Preload ScopeContext and ScopeStack classes in ContinuableScopeManager constructor to avoid class loading on virtual thread mount path. DatadogClassLoader's synchronized I/O from JarFile can pin carrier threads and deadlock the application. (cherry picked from commit c521b50)

…te method Support both afterDone() and afterTerminate() cleanup methods to handle different JDK 21 virtual thread implementations. Both methods cancel the help continuation and release the context scope when the virtual thread completes. (cherry picked from commit d223f79)
