Java primitive arrays with non-native ByteOrder?

[Uwe Schindler]

Hi,

You can try it out and see what happens. From Lucene's point of view i already copied data from a mapped file using MemoryAccess (previously MemoryCopy) with wrong byte order into a float array. Nothing crashed, just bullshit came out.

You may possibly create exceptions on StrictMath methods or strictfp, but we don't use that.
