When doing several requests in parallel , getting a wrong result
I am making several documentSymbol requests in parallel to the jdt, and once in a while I am getting an empty result (for a file which has symbols) and a logMessage error

Any way to handle this error?
Resource '/jdt.ls-java-project/src/com/salesmanager/core/model/user' already exists.
What does your project look like? Are you trying to open the same-named class with different disk location?
This is the project I work on : https://github.com/shopizer-ecommerce/shopizer
I basically create a thread pool of 40 threads and passed all source files and this error happens inconsistently. If I submit each file several times, it always happens (for different files each time) .
How do you import your project?
jdt.ls-java-project is used to hold files which does not belongs to the current workspace, which means the project is not imported correctly.
This is my command to start the jdt ls:
java -Xmx3G -noverify -Declipse.application=org.eclipse.jdt.ls.core.id1 -Dosgi.bundles.defaultStartLevel=4 -Declipse.product=org.eclipse.jdt.ls.core.product -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044 -Dlog.protocol=true -Dlog.level=ALL -javaagent:/source/lombok.jar -jar plugins/org.eclipse.equinox.launcher_1.6.400.v20210924-0641.jar -configuration /config_mac -data /runner/_work/temp/71bdc0c9-c095-40c5-a8c4-c5572c44ec03 --add-modules=ALL-SYSTEM --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED
I then do an initialization request with the following parameters:
{'processId': 43990, 'rootPath': '/runner/_work/temp/71bdc0c9-c095-40c5-a8c4-c5572c44ec03', 'rootUri': 'file:///runner/_work/temp/71bdc0c9-c095-40c5-a8c4-c5572c44ec03', 'initializationOptions': {'extendedClientCapabilities': {'classFileContentsSupport': True}, 'bundles': [], 'workspaceFolders': [], 'settings': {'java': {'references': {'includeAccessors': True}, 'import': {'maven': {'auto': {'sync': True}, 'enabled': False, 'offline': {'enabled': False}}, 'gradle': {'auto': {'sync': True}, 'enabled': False, 'offline': {'enabled': False}}}}}}, 'capabilities': {'textDocument': {'codeAction': {'dynamicRegistration': True}, 'codeLens': {'dynamicRegistration': True}, 'colorProvider': {'dynamicRegistration': False}, 'completion': {'completionItem': {'commitCharactersSupport': False, 'documentationFormat': ['markdown', 'plaintext'], 'snippetSupport': True}, 'completionItemKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]}, 'contextSupport': True, 'dynamicRegistration': True}, 'definition': {'dynamicRegistration': True}, 'documentHighlight': {'dynamicRegistration': True}, 'documentLink': {'dynamicRegistration': True}, 'documentSymbol': {'dynamicRegistration': True, 'hierarchicalDocumentSymbolSupport': True, 'symbolKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]}}, 'formatting': {'dynamicRegistration': False}, 'hover': {'contentFormat': ['markdown', 'plaintext'], 'dynamicRegistration': False}, 'implementation': {'dynamicRegistration': True}, 'onTypeFormatting': {'dynamicRegistration': False}, 'publishDiagnostics': {'relatedInformation': True}, 'rangeFormatting': {'dynamicRegistration': False}, 'references': {'dynamicRegistration': True}, 'rename': {'dynamicRegistration': False}, 'signatureHelp': {'dynamicRegistration': False, 'signatureInformation': {'documentationFormat': ['markdown', 'plaintext']}}, 'synchronization': {'didSave': True, 'dynamicRegistration': False, 'willSave': True, 'willSaveWaitUntil': True}, 'typeDefinition': {'dynamicRegistration': True, 'linkSupport': False}}, 'workspace': {'applyEdit': True, 'configuration': True, 'didChangeConfiguration': {'dynamicRegistration': False}, 'didChangeWatchedFiles': {'dynamicRegistration': False}, 'executeCommand': {'dynamicRegistration': False}, 'symbol': {'dynamicRegistration': True, 'symbolKind': {'valueSet': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]}}, 'workspaceEdit': {'documentChanges': True}, 'workspaceFolders': True}}, 'trace': 'verbose', 'workspaceFolders': [{'name': 'python-lsp', 'uri': 'file:///runner/_work/temp/71bdc0c9-c095-40c5-a8c4-c5572c44ec03'}]}
When I am getting the message:
language/status {'type': 'ServiceReady', 'message': 'ServiceReady'}
I am starting to loop over the java files in the folder and requesting their symbols. When this is done by a single thread everything passes, but if It is done by a thread queue with more than one thread, sometimes one fails. To induce more failure, If I have each file passed more than once (doing more than one symbols request in it) by the thread queue, I get more failures like this.
I just reproduced this. It involved import the project / cleaning workspace and switching in between Lightweight / Standard modes. Also seems similar to https://github.com/eclipse-jdtls/eclipse.jdt.ls/issues/638 .
