I am getting below exception while starting logstash [logstash-1.5.3]. Can any one please help me.

This issue is due to 2 different versions of bouncycastle jars.
One version of jar is located at $JAVA_HOME/jre/lib/ext/bcprov-*.jar
and another is located at logstash
./logstash-1.5.3/vendor/jruby/lib/ruby/shared/org/bouncycastle/bcprov-jdk15on/1.50/bcprov-jdk15on-1.50.jar.
Because of incompatible versions we get this error.

Solution is to overriding the JRE lib/ext folder using -Djava.ext.dirs=/some/dummy/path.
Refer the below link.
