title: cloudfoundry java buildpack memory changes not reflecting
body: <p>I want to make changes in memory settings for my java apps in cloudfoundry java-buildpack. I have tried these two ways:</p>
  
  <ol>
  <li>Using JBP_CONFIG_OPEN_JDK_JRE paramter in my manifest.yml. As
  suggested in
  <a href="https://github.com/cloudfoundry/java-buildpack-memory-calculator" rel="nofollow noreferrer">https://github.com/cloudfoundry/java-buildpack-memory-calculator</a></li>
  <li>Making this change in config\open_jdk_jre.yml:</li>
  </ol>
  
  <blockquote>
    <p>memory_calculator:<br>
    version: 3.8.0_RELEASE<br>
    repository_root:
    "{default.repository.root}/memory-calculator/{platform}/{architecture}"
    stack_threads: 300<br>
     memory_sizes:<br>
    stack: 2M<br>
    metaspace: 160M<br>
    heap: 900M</p>
  </blockquote>
  
  <p>However, none of this is getting reflected while deployment of my apps. I am using latest java-buildpack.</p>
