Ssl WSO2 3.2.0 API管理器收到致命警报：握手失败

我得到以下错误ssl：调用api时，wso2 api manager 3.2.0上的握手失败。我使用keytool添加了证书。下面是我用来添加证书的说明

What is your first and last name?
[Unknown]: axis2a.backend.mytest
What is the name of your organizational unit?
[Unknown]: apim
What is the name of your organization?
[Unknown]: wso2
What is the name of your City or Locality?
[Unknown]: colombo
What is the name of your State or Province?
[Unknown]: A
What is the two-letter country code for this unit?
[Unknown]: LK
Is CN=axis2a.backend.mytest, OU=apim, O=wso2, L=colombo, ST=A, C=LK correct?
[no]: yes

keytool -export -alias wso2am -file wso2am.crt -keystore wso2carbon.jks -storepass wso2carbon

keytool -import -alias wso2am -file wso2am.crt -keystore client-truststore.jks -storepass wso2carbon

当我调用api时，我遇到以下错误

 ERROR - TargetHandler I/O error: Received fatal alert: handshake_failure
javax.net.ssl.SSLException: Received fatal alert: handshake_failure
        at sun.security.ssl.Alerts.getSSLException(Alerts.java:208) ~[?:1.8.0_111]

有什么想法吗？

在这种环境下Java JDK版本是什么？

jdk1.8.0\u 111
