Dear maintainer,

consider the following Scala script test.scala:

  println("Hello, world!")

If I try to run

  $ scala test.scala

I get the following output:

  error: Compile server encountered fatal condition: javax/tools/DiagnosticListener
  java.lang.ClassNotFoundException: javax.tools.DiagnosticListener
  [...]

Interestingly, the call stack differs for repeated executions, so I have not included it here.

Running scala -e 'println("Hello, world!")' produces a similar error message, but executing the code manually in the REPL seems to work.

Although the exception being thrown is a different one, this is probably related to #903140. In particular, I do not have Java 8 installed, and my default Java version is 11.


Please try to have a look at this soon - ideally, this problem should be fixed before the buster freeze, because it really does impact the usability of the package...

Kind regards,
Fabian

Thank you for reporting this issue Fabian. It seems to be a known
upstream bug. The current workaround is to run 'scala -nc test.scala'.

Tested scala 2.12.21+ds3-2 in a clean sid chroot with OpenJDK 25 and no
Java 8. "scala test.scala" (twice, the second time through the running
compile server) and scala -e 'println("Hello, world!")' both print
"Hello, world!" without -nc. Fixed upstream in
https://github.com/scala/bug/issues/10603
