• v0.20.0 Changes

  October 17, 2022

  ➕ Added

  • 0️⃣ Default trait implemented for JObject, JString, JClass, and JByteBuffer (#199)
  • 🚀 Debug trait implemented for JavaVM, GlobalRef, GlobalRefGuard, JStaticMethodID and ReleaseMode (#345)
  • ReturnType for specifying object return types without a String allocation. (#329)

  🔄 Changed

  • The release_string_utf_chars function has been marked as unsafe. (#334)
  • Mark JNIEnv::new_direct_byte_buffer as unsafe (#320)
  • JNIEnv::new_direct_byte_buffer now takes a raw pointer and size instead of a slice (#351 and #364)
  • JNIEnv::direct_buffer_address returns a raw pointer instead of a slice (#364)
  • The lifetime of AutoArray is no longer tied to the lifetime of a particular JNIEnv reference. (#302)
  • Relaxed lifetime restrictions on JNIEnv::new_local_ref. Now it can be used to create a local reference from a global reference. (#301 / #319)
  • 🔀 JMethodID and JStaticMethodID implement Send + Sync and no longer has a lifetime parameter, making method IDs cacheable (with a documented 'Safety' note about ensuring they remain valid). (#346)
  • 🔀 JFieldID and JStaticFieldID implement Send + Sync and no longer has a lifetime parameter, making field IDs cacheable (with a documented 'Safety' note about ensuring they remain valid). (#346)
  • The call_*_method_unchecked functions now take jni:sys::jvalue arguments to avoid allocating a Vec on each call to map + collect JValues as sys:jvalues (#329)
  • 👷 The From trait implementations converting jni_sys types like jobject to JObject have been replaced with unsafe ::from_raw functions and corresponding ::into_raw methods. Existing ::into_inner APIs were renamed ::into_raw for symmetry. (#197)
  • The APIs JNIEnv::set_rust_field, JNIEnv::get_rust_field and JNIEnv::take_rust_field have been marked as unsafe (#219)

• v0.19.0 Changes

  January 24, 2021

  ➕ Added

  • AutoArray and generic get_array_elements(), along with get_<type>_array_elements helpers. (#287)
  • size() method to AutoArray and AutoPrimitiveArray. (#278 / #287)
  • discard() method to AutoArray and AutoPrimitiveArray. (#275 / #287)

  🔄 Changed

  • ✂ Removed AutoPrimitiveArray::commit(). (#290)
  • AutoByte/PrimitiveArray.commit() now returns Result. (#275)
  • Removed methods get/release/commit_byte/primitive_array_{elements|critical}. (#281)
  • Renamed methods get_auto_byte/long/primitive_array_{elements|critical} to get_byte/long/primitive_array_{elements|critical}. (#281)

• v0.18.0 Changes

  September 23, 2020

  ➕ Added

  • JNIEnv#define_unnamed_class function that allows loading a class without
    specifying its name. The name is inferred from the class data. (#246)
  • SetStatic<type>Field. (#248)
  • TryFrom<JValue> for types inside JValue variants (#264).
  • Implemented Copy for JNIEnv (#255).
  • repr(transparent) attribute to JavaVM struct (#259)

  🔄 Changed

  • 🍱 ⚠️ Switch from error-chain to thiserror, making all errors Send. Also, support all JNI errors
    in the jni_error_code_to_result function and add more information to the InvalidArgList
    error. (#242)

• v0.17.0 Changes

  June 30, 2020

  ➕ Added

  • 🚑 Get/ReleaseByteArrayElements, and Get/ReleasePrimitiveArrayCritical. (#237)

• v0.16.0 Changes

  February 28, 2020

  🛠 Fixed

  • 🍎 Java VM instantiation with some MacOS configurations. (#220, #229, #230).

• v0.15.0 Changes

  February 28, 2020

  ➕ Added

  • 👷 Ability to pass object wrappers that are convertible to JObject as arguments to the majority of JNIEnv methods without explicit conversion. (#213)
  • JNIEnv#is_same_object implementation. (#213)
  • JNIEnv#register_native_methods. (#214)
  • 👷 Conversion from Into<JObject> to JValue::Object.

  🛠 Fixed

  • Passing null as class loader to define_class method now allowed according to the JNI specification. (#225)

• v0.14.0 Changes

  October 31, 2019

  🔄 Changed

  • 😌 Relaxed some lifetime restrictions in JNIEnv to support the case when method, field ids; and global references to classes have a different (larger) lifetime than JNIEnv. (#209)

• v0.13.1 Changes

  August 22, 2019

  🔄 Changed

  • 📚 Various documentation improvements.

• v0.13.0 Changes

  July 05, 2019

  0.13 brings major improvements in thread management, allowing to attach the native threads
  permanently and safely; Executor for extra convenience and safety; and other
  👌 improvements and fixes.

  📚 ⚠️ If your code attaches native threads — make sure to check the updated documentation
  📄 of JavaVM to learn about the new features!

  ➕ Added

  • JavaVM::attach_current_thread_permanently method, which attaches the current
    thread and detaches it when the thread finishes. Daemon threads attached
    with JavaVM::attach_current_thread_as_daemon also automatically detach themselves
    when finished. The number of currently attached threads may be acquired using
    JavaVM::threads_attached method. (#179, #180)
  • Executor — a simple thread attachment manager which helps to safely
    🆓 execute a closure in attached thread context and to automatically free
    created local references at closure exit. (#186)

  🔄 Changed

  • 0️⃣ The default JNI API version in InitArgsBuilder from V1 to V8. (#178)
  • Extended the lifetimes of AutoLocal to make it more flexible. (#190)
  • 0️⃣ Default exception type from checked java.lang.Exception to unchecked java.lang.RuntimeException.
    👻 It is used implicitly when JNIEnv#throw is invoked with exception message:
    👻 env.throw("Exception message"); however, for efficiency reasons, it is recommended
    to specify the exception type explicitly and use throw_new:
    🆕 env.throw_new(exception_type, "Exception message"). (#194)

  🛠 Fixed

  • Native threads attached with JavaVM::attach_current_thread_as_daemon now automatically detach
    themselves on exit, preventing Java Thread leaks. (#179)
  • Local reference leaks in JList, JMap and JMapIter. (#190, #191)

• v0.12.3 Changes

  May 24, 2019

  ➕ Added

  • From<jboolean> implementation for JValue (#173)
  • Debug trait for InitArgsBuilder. (#175)
  • InitArgsBuilder#options returning the collected JVM options. (#177)
