JDK 10 Investigation

Query used is this; Generic JEP query is this. (Yes, we may get a JDK 10, 11, etc., after all: Proposal from jdk-dev list) For each Java X (10,11 etc) - add an additional weeks effort for pde related (3d) and misc sanity (2d).

Investigate Java 10 features and the possible support from JDT Core Top Level Bug.

Sl No JEP /JDK Bug Eclipse Bug/Wiki Link Target Milestone/Date Remarks
1 JEP 314: Additional Unicode Language-Tag Extensions Not Applicable - Placeholder
2 JEP 286: Local-Variable Type Inference JEP286: Local Variable Type Inference 3rd March refer JDK-8187694 as well
3 JEP 322: Time-Based Release Versioning Placeholder Feb 23 This may have impact on launcher as well JDT Core model tests (if not covered yet)
4 JSR 269: Pluggable Annotation-Processing API Bug 530444 - JSR 269 API changes 15 Feb Maintenance Release 4 ongoing - keep open.
5 Add -source 10 and -target 10 to javac bug 527556 23 Feb (jdt.core done; jdt.ui has a wip patch and pending - 2d of effort estimated) CSR
6 Add module support for javadoc -link and -linkoffline options to add bug number CSR
7 Support for multiple stylesheets in javadoc to add bug number CSR

JDK 11

Sl No JEP /JDK Bug Eclipse Bug/Wiki Link Target Milestone/Date Effort Estimate Effort Estimate Rationale Remarks
1 JEP 309: Dynamic Class-File Constants 531710 3d jdt.core: disassembler ; no mandatory changes expected for compiler though opportunistically it can generate the new constants - not taking that effort into consideration. No changes expected in jdt.ui and pde. jdt.debug also not affected though the invokedynamic will be used here - no change in jdt.debug atleast in the first phase. targeted
2 JEP 318: Epsilon: An Arbitrarily Low-Overhead Garbage Collector 1d zero if no jdt.debug effort - no effect on jdt.core, jdt.ui and pde. At runtime, a debug session with this option turned on might terminate earlier- the solution could be as simple as bumping up the mem req in which case the effort is low. targeted
3 JEP 320: Remove the Java EE and CORBA Modules 2d test effort only; no effect on JDT and debug - no change in launcher / eclipse.ini file as well as long as we are not using and other deprecated modules - Documentation at the marketplace may require removal of mention of these deprecated modules, if any and use only ALL-SYSTEM. targeted
4 JEP 323: Local-Variable Syntax for Lambda Parameters JEP 323 planning page see also bug 531711 3w See here for details targeted
5 Add -source 11 and -target 11 to javac 531713 4d includes 1d of jdt.core and 2d of estimate of jdt.ui and 1d effort of jdt.debug/launch testing targeted (CSR)
6 Add module support for @see, @link and @linkplain javadoc tags. 531712 2w search, jdt.ui will be affected targeted (CSR)

JDK XX - [11, 12, ...]

Sl No JEP /JDK Bug Eclipse Bug/Wiki Link Target Milestone/Date Effort Estimate Effort Estimate Rationale Remarks
1 JEP 325: Switch Expressions JEP 325 JDT Planning Page see also bug 531714 5w see here for details candidate - highly possible for JDK 11
2 JEP 305: Pattern Matching 531715 8w includes an estimated 5-6w for jdt.core and rest for jdt.ui and debug candidate - highly possible for JDK 11 as an incubating feature
3 Raw String Literals 531716 3w language changes, plus possible refactoring changes. includes a possible 1w effort from jdt.debug changes for breakpoints in between the lines draft - highly possible for JDK 11
4 JEP 302: Lambda Leftovers 0 - placeholder candidate
5 JEP 301: Enhanced Enums 0 - placeholder candidate
6 JEP 293: Guidelines for JDK Command-Line Tool Options 0 - placeholder candidate (Launcher may be affected)
7 JEP 218: Generics over Primitive Types 0 - placeholder candidate
8 JEP 300: Augment Use-Site Variance with Declaration-Site Defaults 0 - placeholder candidate
9 JEP 303: Intrinsics for the LDC and INVOKEDYNAMIC Instructions 0 - placeholder candidate
