Solaris 10上的Cassandra使用不安全的\u GetLong 64位崩溃

我试图在Solaris 10服务器上启动Cassandra节点，但每次尝试创建新列族时，JVM都会以“V[libjvm.so+0x976c08]Unsafe_GetLong+0x120”作为问题帧而崩溃。我使用的是JRE版本：6.0_41-b02，不幸的是，目前无法更新到JRE 7。奇怪的是，如果我删除了-d64选项以将JRE版本切换回32位，我不会得到这个错误，尽管当时我只有2GB的堆空间

我是否可以添加任何JVM选项，将其切换为使用安全的或普通的比较方法，或者有助于JVM在Solaris上更好地处理不安全的方法

更新：

因此，它肯定是64位Solaris SPARC JVM中的一个bug。不幸的是，我找不到任何没有这个bug的JVM版本，也找不到不涉及基本代码的解决方法。我目前的解决方案是检查Solaris 64位，然后进行数组复制，如果是，则使用Guava字典比较程序。这种方法显然比仅仅使用FastByteComparison要慢，但是在我找到一个没有这个bug的JVM版本或者更好的解决方法之前，我必须这样做

private static final boolean useFastByteComparison = !System.getProperty("os.arch").contains("sparcv9");
...
public static int compareUnsigned(byte[] bytes1, byte[] bytes2, int offset1, int offset2, int len1, int len2)
{
    if (useFastByteComparison) {
        return FastByteComparisons.compareTo(bytes1, offset1, len1, bytes2, offset2, len2);
    } else {
        // Short circuit equal case
        if (bytes1 == bytes2 && offset1 == offset2 && len1 == len2) {
          return 0;
        } else {
            byte[] comp1 = new byte[len1];
            byte[] comp2 = new byte[len2];
            System.arraycopy(bytes1, offset1, comp1, 0, len1);
            System.arraycopy(bytes2, offset2, comp2, 0, len2);
            return UnsignedBytes.lexicographicalComparator().compare(comp1, comp2);
        }
    }
}

在那个特定的JVM中看起来像一个bug。

它实际上是JVM bug，而不仅仅是“看起来像”（Java 6/7），我们通过更改…HBase jar文件修复了它。它仅在Solaris 64位上发生

我能够用1.7（JRE版本：7.0_21-b11）测试一个开发系统，看看它是否有帮助。事实并非如此。它有相同的问题框架：V[libjvm.so+0xb9c3e8]Unsafe_GetLong+0x158I下载了1.2.4 src，并添加了一个选项来跳过与系统属性的不安全比较，这样我们至少可以继续使用64位Solaris JVM进行测试，但我觉得这是一个糟糕的解决方案<代码>私有静态最终布尔比较NSAFE=！“false”.equalsIgnoreCase（System.getProperty（“cassandra.compare_unsafe”）我经历了几个JRE版本，但运气不好。是否有一个特定版本的Solaris SPARC JRE已经过测试，并且已知它可以在64位模式下使用不安全的方法工作？看起来SPARC JVM无法处理Unsafe.getLong，因为偏移量不是Longs.BYTES的倍数，并且正在使用ByteBufferUtil.compareUnsigned的偏移量2进行调用。从我添加的日志中：

将^Lbootstrapped与^Lcluster\u名称进行比较，偏移量为2和2，长度为12和12

。Windows和Linux JVM似乎对此没有问题。这确实是JVM错误（Java 6/7），我们通过更改…HBase jar文件修复了它。这种情况只发生在Solaris 64位上。我尝试用Java打开一个bug，但由于没有问题而关闭。看起来他们不支持使用不安全的方法来提取未对齐的内存值。hbase jar文件从哪个版本到哪个版本？你的答案不完整。我们在094.10测试了它。我相信所有以前的版本都会受到影响，不确定。
