KEYWORDS: JNI, Java, ProcessBuilder, Thread Error

ERROR MESSAGE: [os,thread] Failed to start thread - pthread_create failed (EINVAL) for attributes: stacksize: 136k, guardsize: 0k, detached.

SOLUTION: -Djdk.lang.processReaperUseDefaultStackSize=true

DESCRIPTION: 
  From JNI process, it is fine to execute Java internal multi-threading, but can not use Runetime.exec or
  ProcessBuilder to do anything. Even through adjust java stack-realted option
  
  ```
  setenv _JAVA_OPTIONS "-ea -Xlog -XX:ThreadStackSize=31744 -XX:VMThreadStackSize=1024 -XX:CompilerThreadStackSize=1024"
  ```
  
  cgroup (Linux control group) limition, and set_rlimit. Same error message will be displayed.

  When you link large C/C++ program with large thread local storage (TLS), default minimum stacksize computation is not enough
  to create pthread in OS-level. Only to set `-Djdk.lang.processReaperUseDefaultStackSize=true` to apply default pthread arguments.
  Then, it will be working for you.
