Root cause is: java.lang.IllegalStateException: Workspace is closed. This is because SolidityValidator uses the workspace root to determine the unit to compile, while the language server is not started as a headless Eclipse application:

final Set resources = Sets.newHashSet( ResourcesPlugin.getWorkspace().getRoot().findMember(unit.eResource().getURI().toPlatformString(true)));
