Research direction

Start by reproducing the lsp-workspace-command-execute call for workspace/executeCommand with vscode.java.resolveClasspath and inspect the failure involving java.lang.StackTraceElement#classLoaderName. Trace that command to its implementation in lsp-java; done means the classpath command completes without the reported accessibility or TypeAdapter error.
