This error also occurs mainly in Windows. The probability in macOS and linux is small.

Hi @Eskibear, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions

• If you’re using VS Code with the Java Language Server:

  • Run F1 → Java: Clean Java Language Server Workspace to clear corrupted metadata and reload the workspace.
    • Reference: Will not load projects #982 (comment)

• If you’re using the Eclipse IDE:

  • Close Eclipse, back up your workspace.
  • Launch Eclipse with the -clean argument (either via eclipse.ini or eclipse -clean).
  • If issues persist, delete these folders under <workspace>/.metadata/.plugins/org.eclipse.core.resources/:
    • .snap
    • .syncinfo
    • markers
  • Restart Eclipse and let it rebuild the workspace metadata.

Duplicate Issue

• This appears to be the same root cause as “Server crashed when starting from the terminal” where the workspace state is corrupt:
  Server crashed when starting from the terminal  eclipse-jdtls/eclipse.jdt.ls#2851

Other references with low confidence

• EOFException when reading JavaModelManager nonChainingJarsCache suggests cache corruption in JDT core.
  EOFException: Unable to read JavaModelManager nonChainingJarsCache file #951

The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!
