Hi EricCD-S, 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.
It isn’t currently possible to host more than one distinct debug session in a single jdt.ls process—every
startDebuggingcall will reuse the same JDWP port. You have two options:• Spawn a separate jdt.ls process per session. Each instance will pick (or be configured with) its own debug port.
• Switch to “attach” mode and configure multiple debug configurations in your launch.json, each using a different port; then start each JVM with its own-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=<port>.References:
• One jdt.ls instance to handle multiple clients (discusses multiplexing LSP workloads; debug support is similarly single-session per process)
eclipse-jdtls/eclipse.jdt.ls#741Other references with low confidence
• Debug multiple applications running in a single Weblogic server (asks about multiple debug sessions in VS Code; suggests using separate ports/workspaces)
microsoft/vscode-java-debug#1345• Run debug with a single command/click (talks about managing JDWP options in Gradle tasks, not about jdt.ls session multiplexing)

Now if i want to debug different code , i have to start a new jdt.js process to start a debug session. Can i start different debug session in one jdt.ls process to debug different code? i send several start debug session requests to jdt.ls but get the same port number.
