Migration from 2.x to 3.4.2 - Parameters added 4 times?

[csyperski]

Hello, I'm migrating from using version 2.0.12 to 3.4.2 and I'm experiencing problems where my parameters are being set 4 times and I can't figure out why. Below is my mapping as it existed fin 2.0.12, but in 3.4.2, I'm seeing c being populated 4 times so when I get my param it is returning an array.

.addRule(Join.path("/c/{c}/{r}/{more}").to("/customer?c={c}&r={r}&other={more}"))
.addRule(Join.path("/c/{c}/{r}").to("/customer?c={c}&r={r}"))
.addRule(Join.path("/c/{c}").to("/customer?c={c}"))
.addRule(Join.path("/c/").to("/customer"))
.addRule(Join.path("/c").to("/customer"));

In my servlet, I'll see http://xxxx.com/c/1 returning c = [ 1, 1, 1, 1 ]

Am I doing something wrong or is this a bug?
