Array.length in loop condition

Reports accesses to the .length property of an array in the condition part of a loop statement. In highly resource constrained environments, such calls may have adverse performance implications.

This inspection is intended for Java ME and other highly resource constrained environments. Applying the results of this inspection without consideration might have negative effects on code clarity and design.

Example:

void foo(Object[] x) { for (int i = 0; i < x.length; i++) { /**/ } }
