Code actions are not returned when context.only parameter is not empty

[fbricon]

Recent builds of vscode now send code action requests containing a context.only value, like:

Params: {
    "textDocument": {
        "uri": "file:///Users/fbricon/Dev/souk/vertx-demo-david/demo/src/main/java/com/example/DemoApplication.java"
    },
    "range": {
        "start": {
            "line": 30,
            "character": 0
        },
        "end": {
            "line": 30,
            "character": 0
        }
    },
    "context": {
        "diagnostics": [],
        "only": [
            "source"
        ]
    }
}

In https://github.com/eclipse/eclipse.jdt.ls/blob/master/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/text/correction/SourceAssistProcessor.java#L158, context.only values are compared to the code action kind as a whole, instead of checking if the kind has a valid prefix. As a result, no code actions are returned.

All the quickfixes/code actions to extract to a field/var/constant from eclipse-jdtls/eclipse.jdt.ls#1088 are gone.

Nevermind, my problem was that I was selecting new Vets(); instead of new Vets(). That extra semicolon threw me off
