This is urgent - it breaks large number of Fedora Java builds [1] and makes Java applications unusable. [1] http://koschei.cloud.fedoraproject.org/groups/java?order_by=state%2Cname These two builds are the first OpenJDK builds compiled with GCC 5: java-1.8.0-openjdk-devel-1.8.0.40-26.b25.fc2{2,3}.x86_64
(In reply to Severin Gehwolf from comment #2) > These two builds are the first OpenJDK builds compiled with GCC 5: > java-1.8.0-openjdk-devel-1.8.0.40-26.b25.fc2{2,3}.x86_64 Both landed yesterday, since java-1.8.0-openjdk was FTBFS due to bug 1206656 until yesterday. According to [1] F22 has old ABI. F23 breaks this. [1] http://fedoramagazine.org/gcc-5-in-fedora-whats-an-abi-and-what-happens-when-we-change-it/ Created attachment 1010090 [details]

Few more observations. After yesterday build - 26.f22/f23 after long pause because of (arm32 bug 1206656) they do not build itself and are causing this OOM Note packages -26.fc22 fails on both f21 and f23 (no rebuild, just install) Also 25.fc21 works ok on on f21 but on f23 it fails. Failed tasks of java-1.8.0-openjdk trying to build itself with a java-1.8.0-openjdk boot JDK compiled with GCC 5: F22: https://koji.fedoraproject.org/koji/taskinfo?taskID=9398527 rawhide: https://koji.fedoraproject.org/koji/taskinfo?taskID=9398358 This seems to be a problem of java-1.8.0-openjdk built with GCC 5. I've reproduced this issue on F22 too. Offending builds have been untagged. $ koji latest-build f23-build java-1.8.0-openjdk Build Tag Built by ---------------------------------------- -------------------- ---------------- java-1.8.0-openjdk-1.8.0.40-19.b12.fc22 f23 sharkcz $ koji latest-build f22-build java-1.8.0-openjdk Build Tag Built by ---------------------------------------- -------------------- ---------------- java-1.8.0-openjdk-1.8.0.40-19.b12.fc22 f22 sharkcz java-1.8.0-openjdk-1.8.0.40-19.b12.fc22 was the last one built with GCC 4.9. A smaller reproducer seems this (TestCrypoLevel.java comes from java-1.8.0-openjdk sources): $ /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.40-26.b25.fc22.x86_64/bin/javac -d .

So this is starting to look like a JIT bug caused by GCC 5. FWIW, the plain java command line is: ---------------------------- JDK=/path/to/j2sdk-image $JDK/bin/java \ -classpath $JDK/lib/tools.jar:$JDK/classes \ -Dapplication.home=$JDK \ -Xms8m \ com.sun.tools.javac.Main -d . TestCryptoLevel.java ---------------------------- Something is going wrong when java.lang.String::hashCode is getting compiled with C2. Reproducer on a F22 fastdebug build is: JDK=/path/to/j2sdk-image $JDK/bin/java \ -classpath $JDK/lib/tools.jar:$JDK/classes \ -Dapplication.home=$JDK \ -Xms8m \ -XX:+PrintCompilation \ -XX:-TieredCompilation \ -XX:CICompilerCount=1 \ com.sun.tools.javac.Main -d . TestCryptoLevel.java With -XX:+TracePhaseCCP turned on as well and using the reproducer in comment 20 I get this output until the assertion triggers: 83 1 java.lang.String::hashCode (55 bytes) bottom

Created attachment 1015629 [details]
Proposed patch for working around type.o miscompilation.
Patch in comment 30 fixes the problem for me too. No need to set C(XX)FLAGS. I've filed gcc bug 1215127 since I've failed to find the offending snippet in that file. Hopefully gcc people have more luck. Created attachment 1019303 [details] Proposed patch fixing signed integer overflow in type.cpp This patch fixes hotspot to not rely on undefined behaviour.
