Hi, Since yesterday, all Moose-related jobs are failing. These are built on top of Pharo 5.0 stable, downloaded like this: wget --quiet -O - http://get.pharo.org/50+vm | bash We did not change anything in the projects that fail, and locally on Mac, I can load any of the code without problems. The jobs are running Linux. So, I am wondering if anything else has changed in Pharo 5.0. In particular, the error is quite strange. It looks like this: [31mError: MessageNotUnderstood: receiver of "finish" is nil [0mUndefinedObject(Object)>>error: [ :err :rcvr | | errCtx errMorph | errCtx := thisContext. [ errCtx := errCtx sender. "Search the sender chain to find the morph causing the problem" [ errCtx notNil and: [ errCtx receiver isMorph not ] ] whileTrue: [ errCtx := errCtx sender ]. "If we're at the root of the context chain then we have a fatal drawing problem" errCtx ifNil: [ ^ self handleFatalDrawingError: err ]. errMorph := errCtx receiver. ...
