![]() This will change the default value of -illegal-access option from permit to deny. JEP 396: Strongly Encapsulate JDK Internals by Default JEP 395: RecordsĪlready an incubating feature, Records are finalized and becomes a standard feature. JEP 394: Pattern Matching for instanceofĪlready an incubating feature, pattern matching for instanceof is finalized and becomes a standard feature. This update includes a simplified way to perform most common and/or simple tasks with MemoryAccess static class, without a need for VarHandle. JEP 393: Foreign-Memory Access API (Third Incubator)Īlready an incubating feature, Foreign-Memory Access API is refined and still kept as an incubating feature. ![]() Lets see how it is working: $ sudo dpkg -i jep392_1.0-1_b n JEP392 -main-jar JEP392.jar -main-class JEP392 Here is an example on Linux, JEP392.java is in an empty folder and contains a hello world program: $ javac JEP392.java It provides a way to generate platform native packages such as deb and rpm in Linux, pkg and dmg in macOS and msi and exe in Windows. Now it becomes a standard feature and moves to jdk.jpackage module. Packaging Tool, jpackage, was already an incubating feature. Primitive wrapper classes, that are annotated as will have their constructors, which are already marked as deprecated in Java 9, will produce removal warnings. JEP 390: Warnings for Value-Based Classes Warning: using incubating module(s): Īnd it can be run by java (again adding the module manually), pay attention foreign.restricted system property has to be set as well: $ java -add-modules -Dforeign.restricted=permit JEP389 This can be compiled like this (since it is an incubating feature, module has to be added manually): $ javac -add-modules JEP389.java ![]() You look for the library and the method symbol, and bind it to a method handle by providing a function descriptor and method type. Here is an example with OpenJDK 16 Early-Access Build 21 (1): ![]() you need to explicitly use the API) and it is going to be supported only on 圆4 and AArch64 architectures. This feature will not going to provide an auto-vectorization support (i.e. SSE, AVX) and providing a “graceful degradation” to software implementation when SIMD hardware support is not available. SIMD) supported by hardware instructions when available (e.g. This is the first view of incubator module,, that provides vector computation (i.e. The list is taken from the OpenJDK JDK 16 project page. JDK 16 has entered Rampdown Phase One, so the feature set is frozen.
