<Sound Dev> Question about changeset 10209:ef65ddb32456 - maximum chunk size for RIFFReader

[Torsten Krah]

Hi,

i've got some question about this changeset:

http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/ef65ddb32456

There was a check added that the maximum chunk size does not exceed 2
GiB.
Can you tell me the intention of this check? Before this change it was
possible to handle e.g. RIFF Wav-Files which are greater than 2 GiB,
after that change it will result in an exception.

So how to handle files which are greater than 2 GiB now? Downgrading to
JDK 7 or to a version before this change is not a "nice" solution ;-).

Reading about the RIFF-Format the ChunkSize is a uint32_t - 8 Bytes, so
it should be possible to have a 4 GiB file, shouldn't it?

thanks for some enlightenment about this changeset.

thanks and kind regards

Torsten
