Description
springbootVersion=1.5.1.RELEASE
There is a bug in combination with Percentage Encoding for the "%" character.
In combination with the DeferredResult and using @PathVariable.
For any other legal Percentage Encoding it works fine, except for the "%25", i.e. "%" character.
Here is the code snippet:
@RequestMapping(value = "/test/{path_variable}", method = RequestMethod.GET) public DeferredResult<String> test(@PathVariable String path_variable) { DeferredResult<String> response = new DeferredResult<>(); LOG.info("Request for {}", path_variable); try { response.setResult("Hello World"); } catch (Error e) { LOG.debug("Error", e); } catch (Exception e) { LOG.debug("Exception", e); } return response; }
The result is that it takes up to 30000ms to finish the request with an Error 500 code when using "%25" in the PathVariable
