Interesting issue with JRuby 9.2.0.0 and Haml when attempting to evaluate an element attribute with a # just before the interpolated variable.

This is the line which causes the error.

-# app/views/welcome/_partial.html.haml
%p{ data: { target: "##{partial_local_var}" } }

Error:
WelcomesTest#test_visiting_the_index:
ActionView::Template::Error: undefined local variable or method `partial_local_var' for #<Haml::AttributeCompiler:0x9906d99>
    (eval):1:in `<eval>'
    app/views/welcome/index.html.erb:3:in `_app_views_welcome_index_html_erb___706324677_2068'

Using %p{ data: { target: ('#' + partial_local_var.to_s) } } does not throw the error.

I made a test app to demonstrate the error.
