Scott Clasen commented on AMQ-2826:
-----------------------------------
Ok, so I was able to get the adapter to build and test under JDK 1.5 with a
bunch of wrestling. Not sure this is the way to go anyhow, since this would
rely on an external cassandra instance to do testing, and would also be
generally more of a maintenence burden.
Here are the steps I needed to take.
Generate cassandra thrift java sources from the thrift idl, pull into project
(could be an external dependency, but need to compile with jdk1.5) Fix some
blood where generated code was attempting to assign an int instead of an Enum
Type.
Pull BloomFilter and a few dependent sources from cassandra into project,
remove serialization code that ties it to cassandra too strongly. (Could use
another bloomFilter impl or another duplicate detection strategy)
remove two usages of String.getBytes(Charset) and new String(bytes, Charset)
which were added in 1.6 from Cascal (scala cassandra library used in the
adapter), build cascal with jdk 1.5 (skipping tests, since the rely on an
embedded cassandra instance)
install cassandra (actually worked with 0.6.3 even though the thrift api was
0.6.1), configure broker keyspace,
remove adapter test code that relied on embedded cassandra instance, build and
test under jdk 1.5
Sooo, while it is possible to get it working under 1.5, it dosen't feel very
good from a future maintainability and development perspective.
Thoughts?
