# Since Java bytecode and Mach-O fat-files have the same magic number the test
|
|
|
|
|
# must be preformed in the same "magic" sequence to get both right. The long
|
|
|
|
|
# at offset 4 in a fat file tells the number of architectures. The short at
|
|
|
|
|
# offset 4 in a Java bytecode file is the compiler minor version and the
|
|
|
|
|
# short at offset 6 is the compiler major version. Since there are only
|
|
|
|
|
# only 18 labeled Mach-O architectures at current, and the first released
|
|
|
|
|
# Java class format was version 43.0, we can safely choose any number
|
|
|
|
|
# between 18 and 39 to test the number of architectures against
|
|
|
|
|
# (and use as a hack).
