A 32-bit length field read from the wire by CBUtil.readValue (and its
siblings) flowed directly into new byte[length] with no upper bound,
allowing an unauthenticated client to drive the JVM into
OutOfMemoryError: 'Requested array size exceeds VM limit' — and, with
the default -XX:OnOutOfMemoryError=kill -9 %p, terminate the process —
by declaring Integer.MAX_VALUE as the SASL-token length in AUTH_RESPONSE.
Guard the allocation in the single private readRawBytes(ByteBuf, int)
that all int32-length readers funnel through, rejecting lengths that
exceed the buffer's readable bytes with a ProtocolException.

Cassandra resolves pluggable extensions by class name from configuration, schema, and tooling
inputs. These names were loaded with an initializing Class.forName(name) and type-checked only
afterward, so the named class ran its static initializer before its type was confirmed. After this
change such classes will be loaded without initialization, verified against the expected interface or
base class, and initialized only through normal use after validation.
A shared FBUtilities.classForNameWithoutInitialization helper and typed
instanceOrConstruct/construct overloads apply this to the configurable extension points loaded by
class name: the authentication, authorization, role-management, network and
internode-authenticator backends, the partitioner, audit logger, configuration loader, seed provider,
snitch, abstract types, secondary and custom indexes, compaction strategy, compressor, replication
strategy, SASI analyzers, key and cache providers, query handler, storage and stream hooks, tracing,
the JMX authorization proxy, MBeans, the monotonic clock, nodetool Sjk, triggers, the
sstableloader and stress class options, and diagnostic event classes (loaded without initialization
and checked against DiagnosticEvent, preserving the InvalidClassException contract and the existing
package restriction).
Regression tests confirm that an invalid-type load is rejected without initializing the target
class, and that valid implementations still resolve.
Hadoop client integration and hard-coded JDK and internal class probes are left unchanged.

Restore deleteCDCRawFiles logic which is present in 6.0 and trunk but probably lost in 5.0 due to merges
Files may be concurrently removed by the CDC management thread, so we tolerate a file that has already been deleted rather than failing the test.
Fix IndexOutOfBoundsException at commitlog.AbstractCommitLogSegmentManager.forceRecycleAll - it is already fixed in 6.0/trunk.
Cleanup test data after run to reduce disk usage.

When BTreeRow.merge reconciles an update into a row whose existing deletion
shadows the update's cells, it filtered the update (incoming) side of the merge
with Reconciler.retain, which records the removal via
PostReconciliationFunction.delete. On the memtable write path that subtracts the
shadowed cells' on-heap size from the allocator's ownership even though that
incoming data was never allocated to the memtable. Under overwrite/delete churn
that re-applies cells already covered by a newer row/partition deletion (e.g.
repair re-streaming), the allocator's "owns" counter drifts negative and the next
flush trips "AssertionError: Negative released" in MemtablePool$SubPool.released
via MemtableAllocator$SubAllocator.releaseAll during discard.
Filter the update (incoming) side with a non-recording variant,
Reconciler.removeShadowed, and keep retain() for the existing side,
whose data the memtable already owns. The filtered result is identical; only the
erroneous accounting notification is dropped. This mirrors the already-correct
complex-column path in ColumnData.merge.
