Julian Hyde commented on CALCITE-2027: -------------------------------------- I now think that jackson-2.6.5 is too conservative. The latest is jackson-2.9.2, and I see that calcite runs fine with that; I also see from DRILL-5986 that drill is planning to move to jackson-2.7.9.1. Anyone object to jackson-2.9.2? > Drop support for Java 7 (JDK 1.7) > --------------------------------- > > Key: CALCITE-2027 > URL: https://issues.apache.org/jira/browse/CALCITE-2027 > Project: Calcite > Issue Type: Bug > Reporter: Julian Hyde > Assignee: Julian Hyde > Priority: Trivial > > Drop support for Java 7 (also known as JDK 1.7): > * The code would no longer compile under JDK 7 > * Compiler would have source 1.8 target 1.8 > * Class files would run on JDK 8 and higher > * Developers can use Java 8 syntax such as lambdas and default methods > We would continue to build and run under JDK 8 and 9. > I think it would be best to wait a while before converting existing code to > Java 8 style (e.g. converting SAM anonymous classes to lambdas) because code > changes might be extensive. > I expect there will be cases that we want to change interfaces so that they > are easier to use as lambdas. Let's make those changes cautiously when we > come across them, and mark existing interfaces and methods deprecated until > we remove them in 2.0. > Let's give at least one release notice of this change. In 1.15 (the next > release) let's announce that this will be the last release that supports Java > 7. So this will be fixed for 1.16. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
