I believe they have intrinsics even for the long-form Integer.compareTo(Integer.valueOf(a), Integer.valueOf(b)) format which avoids the intermediate allocation.
So this probably won't make things faster, just makes the code a little cleaner.
Integer.compare was added in Java 1.7 which seems safe. Added to Android in SDK 19, which is less than the 21 minSDK supported by protobuf: 303239d74d

We are seeing in profiles that this constructor is calling the other constructor.
It doesn't seem to be totally inlined, as the times spent in each constructor
stack frame are different.
In the common case of no builderParent, the constructor can be empty.

Create WORKSPACE.bzlmod. Before building with Bzlmod resulted in use of full WORKSPACE.
Some repos are still there, but the file should eventually be empty.
Add dep to rules_kotlin 1.9.0. This was the first version available on BCR. It pushed upgrade of
rules_jvm_external to 6.0 and rules_java to 6.5.2 (keep 6.0.0 on Bazel 6.3.0).
Add missing maven and other deps to MODULE.bazel
CI changes:
Disable Bazel 6.4.0 with bzlmod. rules_jvm_external 6.0 use use_repo_rule, which is not supported by Bazel 6.
Add C++ build "Bazel7 with Bzlmod" enabled.
Add Java builds with "Bazel 7 with/without Bzlmod".

These APIs were intended to support an internal-only mutable implementation of Java protobuf and should not actually be used in open source. Removal of these APIs shouldn't break anyone -- the equivalent immutable methods should be used instead.

Looking at the code history, this test used to try two different ways to construct a proto containing map fields, and check that the resulting protos were the same. One of the ways was to obtain mutable `Map` objects for the fields, and modify those. When that possibility was removed from the proto API, the test code that used it was changed to use the other way,
map-modifying methods directly on the proto class. But the end result is that the test method here was just doing the same thing twice and checking that it got the same result.

This is a performance optimisation that avoids us going through from
AbstractList.add(E) to LazyStringArrayList.add(int index, String) and then
having to call the index-based add in ArrayList, which has more bookkeeping
around moving elements across if necessary.
We can avoid that bookkeeping by adding this overload.
Also, group together overloads to squash a style warning.

This should slightly speed things up.
Should be safe: these operations don't change the number of entries inside the loop.

I've made a new name for the interface, ExtensionSerializer, so we can keep ExtensionWriter in the same place for backwards-compatibility for a little while.

These classes are deprecated and will be removed in the next breaking change. Users should update gencode to >= 4.26.x which uses GeneratedMessage instead of GeneratedMessageV3.
Tested with //compatibility:java_conformance_v3.25.0 which builds the runtime against 3.25.0 gencode.

This extends previous workaround for java features in unknown fields, to include features extensions that are known but use a mismatched descriptor.
This can happen when users bring their own descriptors via buildFrom.

This was introduced by the previous fix for delimited inheritance, and was never released. This fix removes all getType() calls from crosslink, where it's not safe to inspect the message type, which is still a placeholder, until after crosslinking. Using the inferred type is not necessary since we treat messages and groups the same during crosslink.

This was previously fixed in C++ (https://github.com/protocolbuffers/protobuf/issues/16549), but not ported to other languages. Delimited field encoding can be inherited by fields where it's invalid, such as non-messages and maps. In these cases, the encoding should be ignored and length-prefixed should be used.

Use old-style for loop instead.
This should speed up processes that serialize many unknown fields, and reduce some GC pressure.

This should not be needed for generated code, but may be needed for user calls to the public buildFrom method. FileDescriptorProto should really be parsed with java features in the extension registry (like other extensions), but we can handle this in Java runtime to ease editions adoption.

This should speed up serializing Extendable Messages (messages with extension ranges declared in their schema) if those message instances have no extensions set inside them at runtime.
