Hi. Are there any recent update with PharoLauncher ? It worked fine yesterday, but today I cannot launch default 8.0 image. It fail with a debug message: Instance of ZnBufferedWriteStream did not understand #name. I'm surprised to receive such message, and can't find out what has change to get suddenly such behaviour. Pharo Launcher is the latest version: Pharo 1.9.2-2019.08.01 - This distribution was built August 01, 2019. I'm using default Pharo 8.0 VM and Image, all refreshed to their latest version. However, the launcher is working well with default Pharo 9.0 VM and Image. Here is an extract of the log (full log attached) Instance of ZnBufferedWriteStream did not understand #name 11 March 2020 10:51:09.200161 am VM: Win32 - IX86 - 10.0 - CoInterpreter VMMaker.oscog-eem.2504 uuid: a00b0fad-c04c-47a6-8a11-5dbff110ac11 Jan 5 2019 StackToRegisterMappingCogit VMMaker.oscog-eem.2504 uuid: a00b0fad-c04c-47a6-8a11-5dbff110ac11 Jan 5 2019 VM: 201901051900 https://github.com/OpenSmalltalk/opensmalltalk-vm.git Date: Sat Jan 5 20:00:11 2019 CommitHash: 7a3c6b6 Plugins: 201901051900 https://github.com/OpenSmalltalk/opensmalltalk-vm.git Image: Pharo7.0.3 [Build information: Pharo-7.0.3+build.158.sha.0903ade8a6c96633f07e0a7f1baa9a5d48cfdf55 (32 Bit)] ZnBufferedWriteStream(Object)>>doesNotUnderstand: #name Receiver: a ZnBufferedWriteStream Arguments and temporary variables: aMessage: name exception: MessageNotUnderstood: ZnBufferedWriteStream>>name resumeValue: nil Receiver's instance variables: stream: BinaryFileStream: 'C:\Users\villemre\devzone\Pharo\images\Pharo 8.0 - 6...etc... buffer: nil position: 0 Any advice ?
