• Visual Studio Code version: 1.49.2
• Java extension version: 0.68.0

Steps To Reproduce

Current Result

List<String> fromJson = new Gson().fromJson("String", new TypeToken<List<String>>() {
}.getType());

@CsCherrYY Could you please take a look at this formatting issue?

Hi, @CarlPer , it seems a formatter version bug. The formatter version of template in vscode-java is 13. And the current version of eclipse is 21. There are some differences between the two versions so your settings may be ignored. We are trying to add a formatter version updater into the language server, and it will make effect at the next jdt version.
Now you can simply replace this setting by <setting id="org.eclipse.jdt.core.formatter.keep_anonymous_type_declaration_on_one_line" value="one_line_if_empty"/> to solve this problem as a workaround.

For anyone else who stumbles onto this issue, I had to add more config:

<setting id="org.eclipse.jdt.core.formatter.keep_type_declaration_on_one_line" value="one_line_if_empty" />
<setting id="org.eclipse.jdt.core.formatter.keep_anonymous_type_declaration_on_one_line" value="one_line_if_empty" />
<setting id="org.eclipse.jdt.core.formatter.keep_method_body_on_one_line" value="one_line_if_empty" />

to support:

class Foo {
  Foo() {}
}

and

class Bar {}

https://github.com/eclipse/eclipse.jdt.ui/blob/master/org.eclipse.jdt.core.manipulation/common/org/eclipse/jdt/internal/ui/preferences/formatter/ProfileVersionerCore.java#L32 mentions the current version as well as a utility method to update older settings to any version.

Update : Ah, I see you found the option as well.

[CsCherrYY]

@rgrunber Yes. eclipse-jdtls/eclipse.jdt.ls@704e50b uses the utility you mentioned to check if there is any need to update the profile.
