Description

In my environment zookeeper is running in fips mode of 3 node cluster. My service is also running in fips mode with security provider org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider

And from the my service when I am trying to connect to zookeeper I am getting the below error.

2021-10-06 17:14:52,645 [nioEventLoopGroup-5-1] WARN  io.netty.channel.ChannelInitializer - opc.request.id=none - Failed to initialize a channel. Closing: [id: 0xa129ece9] -
org.apache.zookeeper.common.X509Exception$SSLContextException: java.security.KeyManagementException: FIPS mode: only SunJSSE TrustManagers may be used
	at org.apache.zookeeper.common.X509Util.createSSLContextAndOptionsFromConfig(X509Util.java:386)
	at org.apache.zookeeper.common.X509Util.createSSLContextAndOptions(X509Util.java:328)
	at org.apache.zookeeper.common.X509Util.createSSLContext(X509Util.java:256)

The reason is the zookeeper has its own trust manager implementation which is

public class ZKTrustManager extends X509ExtendedTrustManager

and jdk also provide a trust manager implementation as below.

X509TrustManagerImpl extends X509ExtendedTrustManager implements X509TrustManager

Because of this hierarchy in SSLContextImpl::chooseTrustManager() method the below instance check become false and hence it falls to the exception block.

if (SunJSSE.isFIPS() && !(var1[var2] instanceof X509TrustManagerImpl)) {
    throw new KeyManagementException("FIPS mode: only SunJSSE TrustManagers may be used");
}
