I want to get InStream for the file specified by a Uri. The following works fine:

f := `file:/path/to/file`.get
in := f.in

But when I try

in := `file:/path/to/file`.get->in

I got an exception:

fan.sys.Method.invoke (Method.java:582)
fan.sys.Method$MethodFunc.callOn (Method.java:230)

Is it a bug?

Promoted to ticket #1576 and assigned to brian

Definitely looks like a bug. Sometimes the reflection code in the sys package gets tricky since it is all mixed up with Java code.

Renamed from NPE when Uri.get->in to Fix Java sys method reflection

Ticket resolved in 1.0.60

I pushed a fix - changeset
