Hi, I'm trying to install some logstash plugin but got errors.

logstash-6.6.0\> bin/logstash-plugin install logstash-output-exec-3.1.4.gem  
LoadError: load error: jopenssl/load -- java.lang.VerifyError: class org.bouncycastle.asn1.ASN1Primitive overrides final method equals.(Ljava/lang/Object;)Z  
require at org/jruby/RubyKernel.java:955

Please help, thanks.
