Comment: was deleted
(was: No, there's no bytes remaining after 0x01.
The exception is raised in the validate(ByteBuffer bytes) function:
215 byte b = bb.get();
216 if (b != 0 && bb.remaining() != 0)
217 throw new MarshalException("Invalid bytes remaining after
an end-of-component at component" +i);
that means if the byte is not 0x00, then this Exception will be raised?
correct me if I am wrong)

Hi,
forgive me if the question is naive.
I'm using the release
0.7(http://svn.apache.org/repos/asf/cassandra/tags/cassandra-0.7.6-2/) and
when I apply the patch , it can't find the file TypeParser.java :
{quote}
$patch -p1 < 0001-Add-compositeType-and-DynamicCompositeType_0.7.patch

patching file src/java/org/apache/cassandra/db/marshal/CompositeType.java
patching file src/java/org/apache/cassandra/db/marshal/DynamicCompositeType.java
can't find file to patch at input line 694
Perhaps you used the wrong -p or --strip option?
