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 --add-modules=java.se.ee 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)
7	Add javac support for preview features	533619		3d		closed (CSR)
8	JEP 327: Unicode 10 Proposed to Target	534657		xd		Targeted
9	JEP 181: Nest-Based Access Control	534668		xd		Candidate

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

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
