Java bouncycastle.jce.provider上的内存泄漏

我正在使用bouncycastle.jce.provider运行一个java（openjdk:11.0.8）应用程序：

group:'org.bouncycastle'，名称：'bcprov-jdk15on'，版本：'1.65'

我注意到内存泄漏，转储显示几乎所有内存都被

javax.crypto.JceSecurity-->java.util.IdentityHashMap

这就是它的样子：

看起来hashMap越来越大了。我在JceSecurity中看到两个身份验证图，其中说明：

// Map<Provider,?> of the providers we already have verified
// value == PROVIDER_VERIFIED is successfully verified
// value is failure cause Exception in error case
private static final Map<Provider, Object> verificationResults =
        new IdentityHashMap<>();

// Map<Provider,?> of the providers currently being verified
private static final Map<Provider, Object> verifyingProviders =
        new IdentityHashMap<>();

我也有同样的问题，我可以用这个小代码解决它。我希望这能帮助某人：）

您可能想查看Saw，但我不知道是否有修复、解决方法或某种替换方法。错误报告中提到了解决方法。仅创建一个

BouncyCastleProvider

的实例似乎不会触发错误。您应该仔细检查您的代码，以确保您没有在某处调用新的BouncyCastleProvider（）。顺便说一句，你的侦探工作做得不错。@PresidentJamesK.Polk-确实有这样的地方。谢谢

static {
    Security.addProvider(new BouncyCastleProvider());
}

public static String encrypt(String pkcs8Base64PublicKey,String text) throws InvalidKeySpecException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
    String publicKeyStr = canonizeKey(pkcs8Base64PublicKey);
    PublicKey publicKey = toPublicKey(publicKeyStr);
    Cipher cipher = Cipher.getInstance(DEFAULT_TRANSFORMATION);
    cipher.init(Cipher.ENCRYPT_MODE, publicKey);
    byte[] encryptedText = cipher.doFinal(text.getBytes(Charset.forName("UTF-8")));
    return new String(Base64.getEncoder().encode(encryptedText), Charset.forName("UTF-8"));
}

public static String decrypt(String pkcs8Base64PrivateKey, String encryptedMessage) throws GeneralSecurityException {
    String privateKeyStr = canonizeKey(pkcs8Base64PrivateKey);
    PrivateKey privateKey = toPrivateKey(privateKeyStr);
    Cipher cipher = Cipher.getInstance(DEFAULT_TRANSFORMATION);
    cipher.init(Cipher.DECRYPT_MODE, privateKey);
    byte[] decryptedMessage = Base64.getDecoder().decode(encryptedMessage);
    return new String(cipher.doFinal(decryptedMessage), Charset.forName("UTF-8"));
}

private static BouncyCastleProvider bouncycastleprovider = null;

public static synchronized BouncyCastleProvider getinstance () {

    if (bouncycastleprovider == null) {

        bouncycastleprovider = new BouncyCastleProvider();

    }
    return bouncycastleprovider;
}
