Bump org.scala-lang:scala-compiler from 2.11.7 to 2.11.12

[dependabot[bot]]

Bumps org.scala-lang:scala-compiler from 2.11.7 to 2.11.12.

Release notes

Sourced from org.scala-lang:scala-compiler's releases.

Scala 2.11.12 is a maintenance release to allow running Scala 2.11 tooling on Java 9. Five pending backports were merged.

This release addresses (#6108) a privilege escalation vulnerability that was identified in the Scala compilation daemon CVE-2017-15288.

We strongly encourage you to upgrade to the latest stable version of Scala 2.12.x, as the 2.11.x series is no longer actively maintained.

There is a known bug on Java 9 involving the repl: the workaround is to launch it as scala -nobootcp.

More general information about the Scala 2.11 series is available in the release notes for Scala 2.11.1.

Thanks to Lightbend for their continued sponsorship of the Scala core team’s efforts. Lightbend offers commercial support for Scala.

Scala 2.11.11: all the way to eleven!

The 2.11.11 release concludes the 2.11.x series, with no further releases planned. Please consider upgrading to 2.12!

Do not use 2.11.9 or 2.11.10, which introduced significant regressions (see below). This also means this series goes to eleven. (No further, though.)

Changes

Significant changes since 2.11.8 include:

• #5730, #5846 Allow custom apply and unapply methods in case class companions. Also allows case class constructors and apply methods to be private. (In 2.11.11, -Xsource:2.12 is needed to enable these changes. In Scala 2.12.2, they are on by default.)
• #5343 Add support for higher order unification under -Ypartial-unification (SI-2712)
• #5341 Fix for higher-kinded GADT refinement
• #5061 JMH-based benchmark framework for contributors
• #5026 Upgrade to newer scala-xml (1.0.5)

2.11.11 resolves regressions introduced in 2.11.9 and 2.11.10: #5730 (fixed by #5828 and #5846), #5664 (fixed by #5821). Special thanks to @​xuwei-k and @​sjrd for reporting and helping diagnose these.

For more information, check out all closed bugs and merged PRs.

As usual for minor releases, Scala 2.11.11 is binary compatible with the whole Scala 2.11 series (with the exception of 2.11.9, which should not be used to publish artifacts, see #5821).
