fluentd-kubernetes-daemonset: fluent can not parse multiline correctly

image version: fluent/fluentd-kubernetes-daemonset:v0.12-debian docker version: 1.12.5 plugin:

# gem list|grep fluent-plugin
fluent-plugin-kubernetes_metadata_filter (0.27.0)
fluent-plugin-multiline-parser (0.1.1)
fluent-plugin-record-reformer (0.9.0)
fluent-plugin-redis (0.2.3)
fluent-plugin-secure-forward (0.4.5)
fluent-plugin-systemd (0.0.8)

after deploying this image via kubernetes daemonsets,i found parser cannot deal with multiline log.

java trancestack log as follows:

2017-08-10 15:12:11.994 [com.pdcss.sfjc.db.DBPool:55] ERROR com.pdcss.sfjc.db.DBPool - Network error IOException: Connection timed out: connect
  java.sql.SQLException: Network error IOException: Connection timed out: connect

   at net.sourceforge.jtds.jdbc.ConnectionJDBC3.<init>(ConnectionJDBC3.java:50)
   at net.sourceforge.jtds.jdbc.Driver.connect(Driver.java:185)

the filter conf like this:

<filter container.error>
      @type parser
      format multiline
      format_firstline /\d{4}-\d{1,2}-\d{1,2}/
      format1 /^(?<time>\d{4}-\d{1,2}-\d{1,2} \d{1,2}:\d{1,2}:\d{1,2}\.\d{0,3}) \[(?<thread>.*)\] (?<level>[^\s]+) (?<classmathod>[^\s]+) - (?<message>[\s\S]*)/
      key_name all
</filter>

as context log said,filter can parser single line log correctly,but incorrectly when parsing multiline such as tracestack. i guess the format param is wrong with the line break(\n) but no idea about this config. by the way,as documentation fluent multiline parser mentioned,format (?<message>.*) also not work. Any solution on this issue,please?
