Search results du(tri)plicated after reindex since 1.1-rc39

[dobrou]

Steps to reproduce:

1. Completely clean the index database and start first indexing
2. Search results are OK
3. Run reindex
4. Search results are duplicated
5. Every next reindex adds duplicate entries. See attached screenshot after second reindex run.
   In indexer it's visible it adds all files as new each time.

Env: Windows, Tomcat, JRE 10.0.2, indexing GIT repositories, Opengrok 1.1-rc39
Opengrok 1.1-rc38 is OK.

My indexer commandline:
java -Xmx5048m -Xms512m --add-modules java.xml.bind -jar .\bin\opengrok-current\lib\opengrok.jar --history -U "http://opengrok/" -R .\configuration-default.xml -W .\configuration-git.xml -P -S -v -s .\sources\git -d .\index\git -p __all__

My xml config:

Seems like some of the Windows fixes broke this. Maybe we can wait for #2335 to be fixed and see if it resolves this problem as well.

[tarzanek]

well yes, uuid is not generated properly now, so lookup will fail and indexer adds new records

[tarzanek]

I will fix this as part of push for #2335, hence closing

Thank you.
