Example log

Looks like scala/scala#11024.

The other failures in the log (search for ComparisonFailException) all seem to be about patterns somehow. Not immediately obvious what could have caused these

[metals] [error] ==> X tests.pc.CompletionCaseSuite.trailing-block_2.13.17-bin-f4ca74b  0.105s munit.ComparisonFailException: tests/cross/src/test/scala/tests/pc/CompletionCaseSuite.scala:103

[metals] [error] Obtained empty output!
