scala.reflect.internal.MissingRequirementError: object scala.runtime.AbstractFunction2 in compiler mirror not found. #7802

Closed scabug closed 11 years ago

scabug commented 11 years ago

Looks like sym.initialize can lead to a MissingRequirementError. Unfortunately, I don't have a reproducible test case, all I have is a stacktrace.

@retronym said: That suggests that scala-library.jar is not in the classpath of that compiler. That seems unlikely, but its the most direct interpretation of the error message. I don't think we can do much more with this without a test case.

@dotta said: The library was definitely there, but I can understand the stacktrace doesn't provide enough clues of what is happening. Will re-open it if I happen to gather more information. Thanks Jason for the quick turnaround.

@retronym said: It could be name table corruption, as we've tried to prevent in the just-merged: https://github.com/scala/scala/pull/2864

@dragos said (edited on Sep 2, 2013 12:52:27 PM UTC): I agree with Jason that name table corruption is the second most likely explanation :)
