Hi dears I have 3 instances of Logstash in my cluster. (version 7.6.2) I upgraded to 7.16.2 one by one But one of the Logstash instance wont work after upgrading: ```auto [FATAL] 2022-01-01 10:36:04.983 [main] Logstash - Logstash stopped processing because of an error: (NameError) cannot link Java class org.apache.http.conn.ssl.SSLConnectionSocketFactory, probable missing dependency: 'boolean org.apache.logging.log4j.spi.LoggerContextFactory.isClassLoaderDependent()' org.jruby.exceptions.NameError: (NameError) cannot link Java class org.apache.http.conn.ssl.SSLConnectionSocketFactory, probable missing dependency: 'boolean org.apache.logging.log4j.spi.LoggerContextFactory.isClassLoaderDependent()' at org.jruby.javasupport.JavaClass.for_name(org/jruby/javasupport/JavaClass.java:292) ~[jruby-complete-9.2.20.1.jar:?] at org.jruby.javasupport.JavaClass.for_name(org/jruby/javasupport/JavaClass.java:288) ~[jruby-complete-9.2.20.1.jar:?] at org.jruby.javasupport.JavaUtilities.get_proxy_class(org/jruby/javasupport/JavaUtilities.java:39) ~[jruby-complete-9.2.20.1.jar:?] at uri_3a_classloader_3a_.jruby.java.core_ext.object.java_import(uri:classloader:/jruby/java/core_ext/object.rb:44) ~[?:?] at org.jruby.RubyArray.map(org/jruby/RubyArray.java:2589) ~[jruby-complete-9.2.20.1.jar:?] at uri_3a_classloader_3a_.jruby.java.core_ext.object.java_import(uri:classloader:/jruby/java/core_ext/object.rb:37) ~[?:?] at RUBY.(/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/manticore-0.7.1-java/lib/manticore/client.rb:89) ~[?:?] at RUBY.(/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/manticore-0.7.1-java/lib/manticore/client.rb:66) ~[?:?] at RUBY.
