I don't know why exactly the Java source would be opened by another process... Maybe an external editor was opened? I've added logging:

#879

If that is not enough we'll need to add more logging info. I'm not sure what type though.

I guess it could be the indexer.

[trancexpress]

I guess it could be the indexer.

Windows search indexer?

I did notice attempts to repeat deleting files, somewhere in the logs... Maybe this is missing here. I'll check tomorrow...

[iloveeclipse]

No, JDT indexer. I guess the test doesn't wait for it.

[trancexpress]

No, JDT indexer. I guess the test doesn't wait for it.

Shouldn't that result in logged exceptions? The Java error is for another process:

java.nio.file.FileSystemException: C:\Users\genie.releng\workspace\AutomatedTests\ep439I-unit-win32-x86_64-java21\workarea\I20260225-1800\eclipse-testing\test-eclipse\eclipse\jdt_folder\StackTest\src\c\Sample.java: The process cannot access the file because it is being used by another process

[iloveeclipse]

I'm not sure the generic message is correct. I believe it wants to say "you delete something someone has open somewhere". So if JDT indexer reads he file while we are deleting test project, delete fails on Windows.

It does seem so: https://stackoverflow.com/a/26741192/13574034

I think the message is from Windows, its not coming from the JDK. Or I don't find the text in the JDK repo.

[iloveeclipse]

OK, so let the test wait for the indexer.

[trancexpress]

OK, so let the test wait for the indexer.

Opened #888, it affects most / all JDT debug tests (that call AbstractDebugTest.waitForBuild()).
