[Bug]: Jruby - Installation failure on jruby due to 'oj' dependency

[ramasangita]

Problem Description

On jruby, 'oj' dependency is added during bundle install. In gemspec, condition is available for jruby to avoid oj dependency but from 1.11.7 version onwards 'oj' is being installed when running bundle

spec.add_runtime_dependency('oj', '>=3.0.11') unless RUBY_PLATFORM =~ /java/i

Issue is not present in 1.11.6 version.

Minimal, Complete, Verifiable, Example

source 'https://rubygems.org'

ruby '3.1', engine: 'jruby', engine_version: '9.4.2.0'

gem 'instana', '>= 1.11.7', require: false gem 'puma' gem 'sinatra' gem 'racksh' gem 'csv'

This is the gem file. 1.11.6 works without any oj dependency but fails with 1.11.7 and later

Pasted Gemfile.lock of working version(1.11.6)
