Eliminate helpless tailing stacktrace is difficult. The exception stack from
ProcBuilder's stderr isn't being captured. The matching rule for the exception
stack is `\tat`, but when stderr outputs the exception, the prefix of the stack
is ` at `. The problem I'm facing could be solved by capturing this part
of the exception stack.
The part of the log that matches the exception is missing the exception
stack.
