I have a following test
test("should create cached thread pool") {
val globalContextMock: LogContextPropagatingEC = mock[LogContextPropagatingEC]
val util = new PaymentExecutionContextImpl with ApplicationConfigTest2 {
override protected lazy val globalExecutionContext = globalContextMock
}
val systemContext = util.systemExecutionContext
assert(!systemContext.eq(globalContextMock), "system execution context should be a new instance, different form global mock")
}
which causes Scala compile the following error:
RangePositions$ValidateException: Synthetic tree [1889] contains nonsynthetic tree [1874]
Anyone knows what causes the issue?
You're compiling with -Yrangepos? If so, and you're using 2.10, it's a bug/issue with the compiler verifying trees that were (probably) modified by macros.
