java 内存泄漏 weblogic AES 充气城堡

我在 WebLogic 上部署了 Web 服务，它利用充气城堡进行 AES 256 位解密。这会导致内存泄漏。我得到的一些日志是这些，

我知道这还不够。对此感到抱歉。谁能解释一下为什么会发生内存泄漏吗？我对 java/security/Provider$ServiceKey 的内存泄漏特别感兴趣。提前致谢。

I have web service deployed on WebLogic which utilizes the bouncy castle to do a AES 256 bit decryption. This is causing a memory leak. A few logs which I have got are these

I know this is not enough information. Sorry about that. Can anyone why is this memory leak happening? I am particularly interested in memory leak dude to java/security/Provider$ServiceKey.
Thanks in advance.

如果有什么区别，请尝试静态安装提供程序。

要静态安装提供程序，您需要将其作为条目添加到 java.security 文件中，该文件位于 $JAVA_HOME/jre/lib/security/java.security您正在使用的 JRE/JDK 的文件夹。在文件中查找包含 security.provider.X 的行列表，其中 X 是某个数字。在列表底部添加以下行：

security.provider.N=org.bouncycastle.jce.provider.BouncyCastleProvider

Try installing the provider statically if that makes any difference.

To install the provider statically, you need to add it as an entry to the java.security file, found in the $JAVA_HOME/jre/lib/security/java.security folder of the JRE/JDK you are using. Look for a list of lines in the file with security.provider.X where X is some number. At the bottom of the list add the line:

security.provider.N=org.bouncycastle.jce.provider.BouncyCastleProvider

我有一个类似的问题 width BouncyCastleProvider，我可以解决它 width this。

private static BouncyCastleProvider bouncycastleprovider = null;

public static synchronized BouncyCastleProvider getInstance () {

    if (bouncycastleprovider == null) {
        bouncycastleprovider = new BouncyCastleProvider();
    }
    return bouncycastleprovider;
}

I had a similar problem width BouncyCastleProvider, and I could solve it width this.

private static BouncyCastleProvider bouncycastleprovider = null;

public static synchronized BouncyCastleProvider getInstance () {

    if (bouncycastleprovider == null) {
        bouncycastleprovider = new BouncyCastleProvider();
    }
    return bouncycastleprovider;
}
