Guess the language by the bug fix

if ("POST".equals(method)) method = "POST";

We don't know whether equality is symmetric in this language. I had that kind of experience at H2O.com, where convincing people that equality has to be an equivalence relationship was just impossible.

[sassa_nf]

It's worse than that here. Somewhere deep in JDK they check for equality instead of equivalence. So the fix is to pass in the thing that will be equal, not just equivalent.

Where do they check it?

BTW, what about `method = method.intern();`?

http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/bedc29a6d074/src/share/classes/sun/net/www/http/HttpClient.java#l275 - this survived into more modern java.

method.intern() can work, if you guarantee it won't intern all possible permutations of upper and lower-case spellings and invalid method names.

OMG.
