This is the right place to report a bug or a minor shortcoming in the Scala 2 compiler, standard library, or language specification.

Atscala/scala3.

Unless you can make a solid, well-supported case that your issue is actually a bug, please ask about it elsewhere first:

• the Scala Users forum;
• the Scala Discord chat server;
• questions tagged with #scala on Stack Overflow.

To keep this tracker focused, we ask that feature requests and discussion of potential language changes take place in thelanguage design category on our contributors forum.

Thank you for finding a bug. We're sorry for the trouble it caused!

When opening an issue here, please:

1. search first to make sure it hasn't already been reported
2. use a small, self-contained snippet of Scala code to illustrate what happened, and contrast with what you expected the compiler to say or the library to do;
3. argue as rigorously as you can, ideally with reference to the language specification or other relevant documentation, that the behavior is actually a bug and not merely surprising or unexpected
4. include the Scala version(s) you tried and the version of the JVM you're using
5. consider trying the same thing in Scala 3, as this can give additional insight

A bug report without a small, self-contained code snippet is much less likely to receive attention.

This repo is separate fromscala/scala because we wanted to preserve the issue numbers from our previous bug trackers, but those numbers conflicted with the pull-request numbers in scala/scala.

The first 10250 issues in this tracker wereimported fromJIRA. We made every attempt to preserve all data and metadata that's supported by the GitHub import API. Sadly, the author metadata could not be preserved directly.

Serious archaeologists can dig up the dusty skeletons of tickets 1-1299 fromAladdin.
