* Fix NPE during encoding and add regression test for issue 9507. (cherry picked from commit58e320a732) * Implement `respond_to?` in RubyMessage (#9677) All synthetic methods implemented by `method_missing` are now supported by `respond_to?`. Fixes issue #9202. * Fix null pointer exceptions exposed by new regression tests. * Fix clear_ on oneofs so that it is safe to call repeatedly and so that respond_to? does not depend on whether the oneof is currently cleared. * Code cleanup: reenable more tests on JRuby. * Align JRuby behavior with CRuby by throwing a RuntimeError when attempting to assign to a oneof. (cherry picked from commit8e7f936696) * Update protobuf version * Merge pull request #9727 from mlocati/build-packaged-php-extension Fix building packaged PHP extension (cherry picked from commit7f9901c5f6) * Update protobuf version * Update changelogs for 3.20.1-rc1 Co-authored-by: Jason Lunn <jason.lunn@gmail.com> Co-authored-by: Jorg Brown <jorg.brown@gmail.com>

Use the Protobuf Java Lite Runtime
The Protobuf Java Lite runtime is separated from the main Java runtime because it's designed and implemented with different constraints. In particular, the Java Lite runtime is much smaller which makes it more suitable to be used on Android.
In order to achieve maximum performance and code size, we do NOT guarantee API/ABI stability for Java Lite. If this is not acceptable for your use-case, use the full Java runtime instead. Note that the latest version of Java Lite is not compatible with the 3.0.0 version.
You can generate Java Lite code for your .proto files:
$ protoc --java_out=lite:${OUTPUT_DIR} path/to/your/proto/file
The "optimize_for = LITE_RUNTIME" option in the .proto file no longer has any effect on Java code.
Include the generated Java files in your project and add a dependency on the protobuf Java Lite runtime. If you are using Maven, include the following:
<dependency>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-javalite</artifactId>
<version>3.20.1-rc-1</version>
</dependency>
R8 rule to make production app builds work
The Lite runtime internally uses reflection to avoid generating hashCode/equals/(de)serialization methods.
R8 by default obfuscates the field names, which makes the reflection fail causing exceptions of the form
java.lang.RuntimeException: Field {NAME}_ for {CLASS} not found. Known fields are [ {FIELDS} ] in MessageSchema.java.
There are open issues for this on the protobuf Github project and R8.
Until the issues is resolved you need to add the following line to your proguard-rules.pro file inside your project:
-keep class * extends com.google.protobuf.GeneratedMessageLite { *; }
