[1.8.0_60-ea-b18 & 1.9.0-ea-b67] Array accesses using sun.misc.Unsafe cause data corruption or SIGSEGV
by Mehmet Dogan 10 Jun '15

10 Jun '15

Hi all, While we were testing an internal project at Hazelcast using 1.8.0_60-ea-b18 & 1.9.0-ea-b67, we encountered a previously reported sun.misc.Unsafe issue. https://bugs.openjdk.java.net/browse/JDK-8076445 http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2015-April/0176… Issue status says it's resolved with resolution "Cannot Reproduce". But unfortunately it's still reproducible using "1.8.0_60-ea-b18" and "1.9.0-ea-b67". Test is very simple: ``` public static void main(String[] args) throws Exception { Unsafe unsafe = findUnsafe(); // 10000 pass // 100000 jvm crash // 1000000 fail int count = 100000; long size = count * 8L; long baseAddress = unsafe.allocateMemory(size); try { for (int i = 0; i < count; i++) { long address = baseAddress + (i * 8L); long expected = i; unsafe.putLong(address, expected); long actual = unsafe.getLong(address); if (expected != actual) { throw new AssertionError("Expected: " + expected + ", Actual: " + actual); } } } finally { unsafe.freeMemory(baseAddress); } } ``` It's not failing up to version 1.8.0.31, by starting 1.8.0.40 test is failing constantly. - With iteration count 10000, test is passing. - With iteration count 100000, jvm is crashing with SIGSEGV. - With iteration count 1000000, test is failing with AssertionError. When one of compilation (-Xint) or inlining (-XX:-Inline) or on-stack-replacement (-XX:-UseOnStackReplacement) is disabled, test is not failing at all. Also, when address calculation in the loop is converted to long address = baseAddress + (i * 8) test passes. Only difference is, next address is calculated using integer 8 instead of long 8. ``` for (int i = 0; i < count; i++) { long address = baseAddress + (i * 8); // <--- here, integer 8 instead of long 8 long expected = i; unsafe.putLong(address, expected); long actual = unsafe.getLong(address); if (expected != actual) { throw new AssertionError("Expected: " + expected + ", Actual: " + actual); } } ``` I tested on versions: - 1.8.0.40 - 1.8.0.45 - 1.8.0_60-ea-b18 - 1.9.0-ea-b67 Previous issue comment ( https://bugs.openjdk.java.net/browse/JDK-8076445?focusedCommentId=13633043#…) says "Cannot reproduce based on the latest version". I hope that latest version is not mentioning to '1.8.0_60-ea-b18' or '1.9.0-ea-b67'. Because both are failing. PS: Cross posted this on 'hotspot-compiler-dev' group but still haven't got a response yet. http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2015-June/01819… Thanks, Mehmet Dogan -- @mmdogan

Early Access builds for JDK 9 b66 and JDK 8u60 b18 are available on java.net
by Rory O'Donnell 05 Jun '15

05 Jun '15

Hi All, Early Access build for JDK 8u60 b18 <http://jdk8.java.net/download.html> is available on java.net, summary of changes are listed here. <http://www.java.net/download/jdk8u60/changes/jdk8u60-b18.html> As we enter the later phases of development for JDK 8u60, please log any show stoppers as soon as possible. Early Access build for JDK 9 b66 <https://jdk9.java.net/download/> is available on java.net, summary of changes are listed here <http://www.java.net/download/jdk9/changes/jdk9-b66.html>. The JDK 9 schedule of record is available on the JDK 9 Project page: http://openjdk.java.net/projects/jdk9 At https://wiki.openjdk.java.net/display/Adoption/JDK+9+Outreach you can find a (preliminary) list of other changes that might affect your project's code in JDK 9, and other things to consider when testing with JDK 9. I'd be curious to know if there is anything on that list you'd consider to have an effect on your project. Please keep in mind that as JEPs and others changes are integrated into (or out of) JDK 9, the list will change over time.
