環境
開発環境と実行環境は別です開発環境
Windows 7 64bit
eclipse 4.6.1
com.google.cloud google-cloud-pubsub 0.25.0-beta
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
実行環境
CentOS 7
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)
原因と対処法
実はWindowsのJava(TM) SE Runtime Environment環境だと問題なく動く。CentOS 7のOpenJDK環境でのみエラーが発生する。
yum update java を実行してOpenJDKをアップデート
アップデート後のopenJDK
OpenJDK Runtime Environment (build 1.8.0_144-b01)
OpenJDK 64-Bit Server VM (build 25.144-b01, mixed mode)
OpenJDKをアップデートしたところ、エラーが出なくなった。
