With the change to useLoadForParent=false by default a problem has shown up

Adrian Brock commented on JBCL-142:
-----------------------------------
The issue only occurs when there is a security manager and there is some access control
logging
and only because a class in stdio needs to load java.lang.Math which is not already
loaded.
It doesn't occur with useLoadClassForParent=true because loadClass() doesn't do
any
access control logging.
Read the comments in the stacktrace from the bottom upwards to see what is happening.

----------------------------------
Updated stdio to not use Math.min, so perhaps this issue will just disappear.
