Summary

// REQUIRED -- Provide a short summary of the proposal, at most one or two // sentences. This summary will be rolled up into feature lists, JSRs, and // other documents, so please take the time to make it short and sweet.

Goals

// What are the goals of this proposal? Omit this section if you have // nothing to say beyond what's already in the summary.

Non-Goals

// Describe any goals you wish to identify specifically as being out of // scope for this proposal.

Success Metrics

// If the success of this work can be gauged by specific numerical // metrics and associated goals then describe them here.

Motivation

// Why should this work be done? What are its benefits? Who's asking // for it? How does it compare to the competition, if any?

Description

// REQUIRED -- Describe the enhancement in detail: Both what it is and, // to the extent understood, how you intend to implement it. Summarize, // at a high level, all of the interfaces you expect to modify or extend, // including Java APIs, command-line switches, library/JVM interfaces, // and file formats. Explain how failures in applications using this // enhancement will be diagnosed, both during development and in // production. Describe any open design issues. // // This section will evolve over time as the work progresses, ultimately // becoming the authoritative high-level description of the end result. // Include hyperlinks to additional documents as required.

Alternatives

// Did you consider any alternative approaches or technologies? If so // then please describe them here and explain why they were not chosen.

Testing

// What kinds of test development and execution will be required in order // to validate this enhancement, beyond the usual mandatory unit tests? // Be sure to list any special platform or hardware requirements.

Risks and Assumptions

// Describe any risks or assumptions that must be considered along with // this proposal. Could any plausible events derail this work, or even // render it unnecessary? If you have mitigation plans for the known // risks then please describe them.

Dependencies

// Describe all dependencies that this JEP has on other JEPs, JBS issues, // components, products, or anything else. Dependencies upon JEPs or JBS // issues should also be recorded as links in the JEP issue itself. // // Describe any JEPs that depend upon this JEP, and likewise make sure // they are linked to this issue in JBS.
