* java/lang/natClass.cc (_Jv_IsAssignableFrom): Ensure that ancestors
table index is within allowed bounds. Ensure that we dont try to access
class itable at a negative offset. Avoid an ancestor table lookup if
source is a primitive type class.
(isInstance): Remove redundant isPrimitive() check.

overflow/underflow. Instead, trim whitespace, and then check that
_strtod_r uses up all the rest of the string.
From-SVN: r40800
* java/lang/natClass.cc (_Jv_IsAssignableFrom): Checking the
ancestors array is invalid for interfaces, so do that *after*
