----------------------------------------
Summary: Cassandra crashes on Solaris sparcv9 using java 64bit
Key: CASSANDRA-6628
URL: https://issues.apache.org/jira/browse/CASSANDRA-6628
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: checked 1.2.x line and 2.0.x
Reporter: Dmitry Shohov
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.
