To make clear - the very first build using the task passes. The rest fail.

Hi @MarkKharitonov! I tried to reproduce this. Partially successful, but the error message is different from what is contained in the description. Could you please provide the content of your azure-pipelines.yml file? It was also noticed that such an error message occurs when there is no access to the source archive with Java. Could you make sure that the file is available at the task execution moment?

I have worked around the problem by copying the zip file locally. The code I finally use is this:

steps:
- task: CopyFiles@2
  displayName: 'Copy JRE zip'
  name: CopyJREZip
  inputs:
    SourceFolder: '\\$(fileShareServer)\ToolInstallationsForAzureDevOps'
    Contents: 'server-jre-8u231-windows-x64.tar.gz'
    TargetFolder: '$(TEMP)'

- task: JavaToolInstaller@0
  inputs:
    versionSpec: '8'
    jdkArchitectureOption: 'x64'
    jdkSourceOption: 'LocalDirectory'
    jdkFile: '$(TEMP)\server-jre-8u231-windows-x64.tar.gz'
    jdkDestinationDirectory: '$(Build.ArtifactStagingDirectory)\java'
    cleanDestinationDirectory: false

I do not have cycles to investigate it any further.
