Question

我一直在研究用Linux（x86）运行的Java编写的程序多年，现在将其移植到Linux（ARM）上。我正面临一个问题，不知道它来自哪里。

使用

在Slackware 12.1（x86）上运行示例时

# java -version
java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

它运行得非常好。使用

在Slackware 14.1（ARM）上运行时

# java -version
java version "1.7.0_13"
OpenJDK Runtime Environment (IcedTea7 2.3.6) (Slackware)
OpenJDK Zero VM (build 22.0-b10, mixed mode)

我得到一个例外：

# java -jar SpectoTechnologies_TestHTTP.jar

问题很可能与Oracle / Sun JRE与OpenJDK的代码不兼容......或Linux上缺少的东西（SSL包或其他东西）有关，但找不到类似的东西的答案。

我已经制作了一个SSCCE来重现这个问题：

package com.spectotechnologies.tests;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import java.io.StringWriter;
import java.io.Writer;
import java.net.HttpURLConnection;
import java.net.Proxy;
import java.net.URL;

/**

public class HTTP
{
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        try
        {
            InputStream oInput;
            URL oURL = new URL("https://google.com");

            HttpURLConnection oConnection = (HttpURLConnection)oURL.openConnection(Proxy.NO_PROXY);

            oConnection.setDoOutput(true);
            oConnection.setDoInput(true);
            oConnection.setRequestMethod("GET");

            if(oConnection.getResponseCode() != 500)
            {
                oInput = oConnection.getInputStream();
            }
            else
            {
                oInput = oConnection.getErrorStream();
            }

            String sResult = convertStreamToString(oInput);

            System.out.println(sResult);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

    }

    public static String convertStreamToString(java.io.InputStream is) throws IOException
    {
        if(is != null)
        {
            Writer writer = new StringWriter();

            char[] buffer = new char[1024];

            try
            {
                Reader reader = new BufferedReader(new InputStreamReader(is,"utf-8"));
                int n;

                while ((n = reader.read(buffer)) != -1)
                {
                    writer.write(buffer, 0, n);
                }
            }
            finally
            {
                is.close();
            }

            return writer.toString();
        }
        else

            return "";
        }
    }

解析配置文件$JAVA_HOME/lib/security/java.security时会引发错误。有几个错误与此有关。

java.security.ProviderException: Error parsing configuration with space

sun.security.pkcs11.ConfigurationException: Unexpected value Token ['(']

我的猜测是你的配置文件中有特殊字符或空格，这些字符或空格在jvm的一个版本中正确解释，而在另一个版本中没有。
