How can we reproduce the losing jobserver token issue? I tried the following steps, however, no such messages appeared. 1) git clone https://git.openjdk.java.net/jdk/ 2) cd jdk 3) export TEMP=/tmp 4) bash configure 5) make images The summary of the configuration is as follows: Configuration summary: * Name: windows-x86_64-server-release * Debug level: release * HS debug level: product * JVM variants: server * JVM features: server: 'cds compiler1 compiler2 epsilongc g1gc jfr jni-check jvmci jvmti management parallelgc serialgc services shenandoahgc vm-structs zgc' * OpenJDK target: OS: windows, CPU architecture: x86, address length: 64 * Version string: 19-internal-adhoc.yano.jdk (19-internal) * Source date: Determined at build time Tools summary: * Environment: cygwin version 3.3.5-341.x86_64, 2022-05-13 12:27 UTC; windows version 10.0.19044.1706; prefix "/cygdrive"; root "C:\cygwin64" * Boot JDK: java version "18" 2022-03-22 Java(TM) SE Runtime Environment (build 18+36-2087) Java HotSpot(TM) 64-Bit Server VM (build 18+36-2087, mixed mode, sharing) (at /cygdrive/c/progra~1/java/jdk-18) * Toolchain: microsoft (Microsoft Visual Studio 2022) * C Compiler: Version 19.32.31329 (at /cygdrive/c/progra~1/micros~1/2022/commun~1/vc/tools/msvc/1432~1.313/bin/hostx86/x64/cl.exe) * C++ Compiler: Version 19.32.31329 (at /cygdrive/c/progra~1/micros~1/2022/commun~1/vc/tools/msvc/1432~1.313/bin/hostx86/x64/cl.exe) Build performance summary: * Build jobs: 8 * Memory limit: 16136 MB $ cygcheck -c autoconf make zip unzip Cygwin Package Information Package Version Status autoconf 15-1 OK make 4.3-1 OK unzip 6.0-17 OK zip 3.0-12 OK -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
