Hi, I can see what @niabot says. In my case NetBeans does not "hang", but
can't delete the last `}` in the given example.
I'll try to take a look at it later on.
For the record, here's the message I get in the IDE Log:
```txt
SEVERE [global]
java.lang.IllegalStateException: Lexer
org.netbeans.modules.languages.toml.TomlLexer@419edac2
returned null token but lexerInput.readLength()=2
lexer-state: -1
tokenStartOffset=85, readOffset=87, lookaheadOffset=88
Chars: "\n\n" - these characters need to be tokenized.
Fix the lexer to not return null token in this state.
