we’ve recently upgraded our staging environment from R106 to R109.
we are using the batch pipeline, executing it hourly via cron.
since the upgrade to R109, around 1/3 of these runs fail with the following error message:
uri:classloader:/gems/avro-1.8.1/lib/avro/schema.rb:350: warning: constant ::Fixnum is deprecated
uri:classloader:/gems/json-schema-2.7.0/lib/json-schema/util/array_set.rb:18: warning: constant ::Fixnum is deprecated

require at org/jruby/RubyKernel.java:970
require at uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:59
any idea what is the reason for it & how to solve it?
we are holding back the upgrade of the production env till it’ll be solved.
thabks a lot in advance for your help!
