With 3.0 we can start specializing generators (and parsers too) more, due to full immutability of feature flags. One thing that should allow minor performance optimization is separating "non-vanilla" feature...

Include forward slash ('/') as character to escape by default in String values

2

Jackson 2.x only escapes minimum set of characters, as defined by JSON specification. This does not include forward slash character ('/'). But while legal, it turns out that more often...

As of Jackson 2.x, `PrettyPrinter` interface is overloaded with `Instantiable` "mix-in" -- so `PrettyPrinter` that is registered is either: 1. Used as-is, if impl does not implement `Instantiatable`. This works...

Improve buffer recycling for platforms that have broken SoftReference (Android)

5

Since Google seems unable to provide sane handling for SoftReferences, perhaps we can work-around this issue to some degree, at least for a relatively common case of single-threaded reuse. The...

Support Gradle 6 version alignment with Jackson Scala module (`jackson-module-scala`)

4

(as background, see https://github.com/FasterXML/jackson-databind/issues/2726) So, Jackson 2.12 is adding support for Gradle version alignment, using mechanism supported by Gradle 6. @jjohannes contributed this for other modules and hopefully can help,...

Support type visitability (for JSON Schema module) for Scala Collections, Maps, Option

1

(note: copied from https://github.com/FasterXML/jackson-module-jsonSchema/issues/71) Looks like Scala types may not (fully?) support visitability, to allow things like JSON Schema generation. Adding support is relatively easy, as it only requires implementation...

Consider performance improvements for Date/Time parsing

2

Jsoniter project (https://github.com/plokhotnyuk/jsoniter-scala) has many impressive performance optimizations; linked f.ex from here: https://www.reddit.com/r/java/comments/darehu/jackson_release_210/f1ysf1e/ and ones relevant to this repo have to with Java 8 date/time type decoding. It would be...

`OffsetDateTime` deserialization does not handle nano seconds correctly

9

(moved from https://github.com/FasterXML/jackson-datatype-jsr310/issues/96 by @xzer) when InstantDeserializer get a long value for OffsetDateTime, it will entering the following method: ```java protected T _fromLong(DeserializationContext context, long timestamp) { if(context.isEnabled(DeserializationFeature.READ_DATE_TIMESTAMPS_AS_NANOSECONDS)){ return fromNanoseconds.apply(new...

(datatypes) Support of JavaFX collections

8

(moved from existing issue reported by @agonist) Hi, refering to this issue FasterXML/jackson-databind#718 I'd like to suggest to add support for JavaFX collections since it included in JDK8. http://docs.oracle.com/javase/8/javafx/api/javafx/beans/property/ListProperty.html http://docs.oracle.com/javase/8/javafx/api/javafx/collections/ObservableList.html...

(date/time) Support `jackson-datatype-Threetenbp` fork?

7

(move from https://github.com/FasterXML/jackson-datatype-jsr310/issues/90 by @cbornet) ------ The [threetenbp](https://github.com/joschi/jackson-datatype-threetenbp) fork doesn't seem very lively and hasn't been updated since jackson 2.6.4. Could FasterXML provide its own threetenbp implementation or maintain this...
