残念ながら Scala 2.10.0 でリリースされた現行の状態ではリフレクションはスレッドセーフではない。
[SI-6240](https://issues.scala-lang.org/browse/SI-6240) が報告されているので、それを使って進捗を追跡したり、技術的な詳細を照会することができるが、ここに現状で分かっていることをまとめてみたい。

<span class="label success">NEW</span> Thread safety issues have been fixed in Scala 2.11.0-RC1, but we are going to keep this document available for now, since the problem still remains in the Scala 2.10.x series, and we currently don't have concrete plans on when the fix is going to be backported.

There's a JIRA issue [SI-6240](https://issues.scala-lang.org/browse/SI-6240), which can be used to track our progress
and to look up technical details, and here's a concise summary of the state of the art.

<span class="label success">NEW</span> Thread safety issues have been fixed in Scala 2.11.0-RC1, but we are going to keep this document available for now, since the problem still remains in the Scala 2.10.x series, and we currently don't have concrete plans on when the fix is going to be backported.

Currently we know about two kinds of races associated with reflection. First of all, reflection initialization (the code that is called
when `scala.reflect.runtime.universe` is accessed for the first time) cannot be safely called from multiple threads. Secondly, symbol
initialization (the code that is called when symbol's flags or type signature are accessed for the first time) isn't safe as well.
