`builder.redirectError(Redirect.INHERIT)` would consuming the error output
from buffer and then print it to stderr (inherit the target from the current
Scala process).
If without this there would be 2 issues:
1) The error msg generated by the script process would be hidden.
2) If the error msg is too big to be hold by the buffer, the input logic
would be hang (There's are simple steps on jira to reproduce this behavior).
