Local fix

  • To force a specific number of compilation threads a JIT option

Problem summary

    option -XcompilationThreads<nnn> is not working correctly and,
    if used, 4 compilation threads will be created regardless of the
    specified value.
    

Problem conclusion

    .
    The bug has been fixed in the JIT so that the option is useful
    again.
