Features
This page describes the changes introduced within each version.
Language-related changes should normally have a validator, used in conjunction with the grammar, as part of the parsing process.
Where a change is not a language-related change (e.g. JVM and garbage collection changes), this is marked as “Not Applicable (NA)”.

- JSR 335, JEP 126: Language-level support for lambda expressions (officially, lambda expressions; unofficially, closures) under Project Lambda and default methods (virtual extension methods) which allow the addition of methods to interfaces without breaking existing implementations. There was an ongoing debate in the Java community on whether to add support for lambda expressions. Sun later declared that lambda expressions would be included in Java and asked for community input to refine the feature. Supporting lambda expressions also enables functional-style operations on streams of elements, such as MapReduce-inspired transformations on collections. Default methods allow an author of an API to add new methods to an interface without breaking the old code using it. Although it was not their primary intent, default methods also allow multiple inheritance of behavior (but not state).
- JSR 223, JEP 174: Project Nashorn, a JavaScript runtime which allows developers to embed JavaScript code within applications
- JSR 308, JEP 104: Annotation on Java types, Unsigned integer arithmetic

- JEP 122: Remove the permanent generation
JDK 9 - September 2017
Source: https://en.wikipedia.org/wiki/Java_version_history#Java_SE_9
- JSR 376: Modularization of the JDK under Project Jigsaw (Java Platform Module System)
- JEP 222: JShell: The Java Shell (a Java REPL)
- JEP 295: Ahead-of-time compilation
- JEP 268: XML catalogs
- JEP 266: More concurrency updates. It includes a Java implementation of Reactive Streams, including a new Flow class that included the interfaces previously provided by Reactive Streams
- JEP 193: Variable handles: define a standard means to invoke the equivalents of various java.util.concurrent.atomic and sun.misc.Unsafe operations
- JEP 282: jlink: The Java Linker: create a tool that can assemble and optimize a set of modules and their dependencies into a custom run-time image. It effectively allows to produce a fully usable executable including the JVM to run it. JavaDB was removed from JDK
- JEP 263: HiDPI graphics: automatic scaling and sizing

Footnotes:
- JEP181 - Based on a cursory reading of this JEP, it is unclear if this is a change that affects JavaParser. Comments/discussion on this are welcomed. ↩
- JEP327 - Based on a cursory reading of this JEP, it is unclear if this is a change that affects JavaParser. Comments/discussion on this are welcomed. ↩
- JEP320 - JEP 320 is marked as NA. This is because JavaParser does not make use of classes within these packages, and any users of JavaParser will need to provide the relevant files in order to do parsing/solving (e.g. as source files, a jar, or via reflection). ↩

Footnotes:
- JEP343 - JEP 343 is marked as not applicable, as it relates to packaging of apps - e.g. as
.exe/.msi/.deb/.rpm/.pkg/.dmg. The JEP describes the layout/structure of the output file, suggesting that maybe in the future the files may be examined, and potentially used similarly to a .jar or set of .class files. This is not going to be actively pursued (especially since this is still in the incubator stage), though tested PRs are always welcome. ↩
