> Key: CASSANDRA-6628

> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: checked 1.2.x line and 2.0.x

> When running cassandra 2.0.4 (and other versions) on Solaris and java 64 bit,
> JVM crashes. Issue is described once in CASSANDRA-4646 but closed as invalid.
> The reason for this crash is some memory allignment related problems and
> incorrect sun.misc.Unsafe usage. If you look into DirectByteBuffer in jdk,
> you will see that it checks os.arch before using getLong methods.
> I have a patch, which check for the os.arch and if it is not one of the
> known, it reads longs and ints byte by byte.
> Although patch fixes the problem in cassandra, it will still crash without
> similar fixes in the lz4 library. I already provided the patch for Unsafe
> usage in lz4.
