+1. Nice catch. Feels like an implementation detail, but the JVM specification is indeed unclear on the behavior in case there's a bytecode method doing this: public static func(I)Z 0 iload 0 1 ireturn I went spelunking in the JVM spec, and the closest I could find is in section 2.3.4 says "The Java Virtual Machine encodes boolean array components using 1 to represent true and 0 to represent false. Where Java programming language boolean values are mapped by compilers to values of Java Virtual Machine type int, the compilers must use the same encoding." So I guess we better stick to that.
