Java运行时错误SIGBUS iText

我正在尝试使用iText 5.5.0和文档示例进行签名：

private static void pdfSign(String srcFile, String dstFile) throws Exception

    KeyStore ks = KeyStore.getInstance("pkcs12", "BC");
    ks.load(new FileInputStream(PFX_ROUTE), PFX_PASSPHRASE);
    String alias = (String)ks.aliases().nextElement();
    PrivateKey pk = (PrivateKey)ks.getKey(alias, KEY_PASSPHRASE);
    Certificate[] chain = ks.getCertificateChain(alias);
    // reader and stamper
    PdfReader reader = new PdfReader(srcFile);
    PdfStamper stamper = PdfStamper.createSignature(reader, new FileOutputStream(dstFile), '\0');
    // appearance
    PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
    appearance.setVisibleSignature(SIGNFIELD_NAME);
    appearance.setReason("Test");
    appearance.setLocation("TestLocation");


    ExternalSignature es = new PrivateKeySignature(pk, "SHA-1", "BC");
    ExternalDigest digest = new BouncyCastleDigest();
    MakeSignature.signDetached(appearance, digest, es, chain, null, null, null, 0, CryptoStandard.CMS);
}

我得到以下错误

我的java版本是：

java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

我正在使用Netbeans IDE 7.4和在my/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre/lib/security path中替换的JCE Unlimited Strength辖区策略文件

我已经在终端上尝试了“ulimit-c unlimited”命令

我不知道为什么，我在另一个环境中尝试了我的代码，它给了我一个BouncyCastle异常。我将BC JAR更改为1.48版本，它在我的Windows环境中正常工作。在我的Unix环境中，保存文件时遇到问题

感谢所有

请显示

hs_err_pid602.log的内容

。在此处添加内容：Hhmmm，

sun.misc.Unsafe.copyMemory

似乎经常涉及有趣的JVM崩溃。您可能希望尝试不同的

PdfReader

构造函数，例如，首先将文件读入内存，然后使用带有

byte[]

参数的构造函数。您是否尝试过这种方法，仍然存在相同的错误。或者，您是否尝试过不同的jvm版本？由于iTextin在您的用例中只使用标准api调用，这很可能是Java错误。
