Enhances ZGC to support concurrent thread-stack processing.
Provides an API to allow Java programs to safely and efficiently access foreign memory. This JEP proposes the removal of the Java EE and CORBA modules from the JDK. Introduces a new rendering pipeline for mac OS. Introduces sealed classes and interfaces to restrict which classes can extend or implement them. Text blocks are a new way to declare multi-line string literals. Introduces a new syntax for multi-line string literals. Provides a mechanism for Java programs to safely and efficiently access foreign memory. Multi-line string literals. Introduces text blocks as a new way to declare multi-line string literals. Provides a new syntax for multi-line string literals. |
