Invalid ranges for options

Hi,

As SAP JVM is has some different default settings, TestOptionsWithRanges.java has
detected two problematic ranges:
  java -XX:MaxJNILocalCapacity=1 -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044
  java -XX:+SafepointTimeout -XX:SafepointTimeoutDelay=0

I think the ranges of MaxJNILocalCapacity and SafepointTimeoutDelay should be fixed.
Should I open a bug for this?

Best regards,
  Goetz.
