Yes, change your proxy server to nginx
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-tomcat-platform.html#java-tomcat-platform-configfiles
I used the "Example .ebextensions/tomcat-settings.config"

option_settings:
  aws:elasticbeanstalk:container:tomcat:jvmoptions:
    Xms: 512m
    Xmx: 512m
    JVM Options: '-Xmn128m'
  aws:elasticbeanstalk:application:environment:
    API_ENDPOINT: mywebapi.zkpexsjtmd.us-west-2.elasticbeanstalk.com
  aws:elasticbeanstalk:environment:proxy:
    GzipCompression: 'true'
    ProxyServer: nginx
  aws:elasticbeanstalk:environment:proxy:staticfiles:
