> The {{JavaScriptStripper}} fails to accurately detect regular expressions in some cases.
> In the example below it fails to switch into the {{REG_EXP}} state at '{{{}return/[{}}}', and will then switch to {{LINE_COMMENT}} state when parsing '{{{}//{}}}', which will then lead to the entire rest of the JavaScript code to be cut off, making the code unparseable by the client.
> {{return/[-a-zA-Z0-9@:%._\+~#=]\{2,256}\.[a-z]\{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)/gi.test(t)}};}}
> An example of a webjar containing javascript, that will trigger the bug can be found here: [https://search.maven.org/artifact/org.webjars.npm/summernote/0.8.20/jar] - also see attached JS files below.
> Current workaround is to disable compression:
> getResourceSettings().setJavaScriptCompressor(null);
