    Description

      This is related to the GString equality issues, but is an issue on its own.

      This might cause nasty side effects.

BigDecimal a = 2.0
BigDecimal b = 2.00

println a.equals(b) // false
println(a.compareTo(b)) // 0
println a == b // true

println([a].equals([b])) // true, which is different from Java, which would return false!

      I think Groovy should try to behave 100 percent like Java in such contexts.
