NullPointerException at YetiTypeAttr$DecodeType.read when loading module

[chrisichris]

Hi,

I get the following exception when loading mongo module (
https://github.com/chrisichris/yeb/blob/master/src/org/yeb/mongo.yeti
) from the repl:

Yeti 0.9.4+ REPL.

> load org.yeb.mongo
java.lang.NullPointerException
at yeti.lang.compiler.YetiTypeAttr
$DecodeType.read(YetiTypeAttr.java:281)
at yeti.lang.compiler.YetiTypeAttr
$DecodeType.readMap(YetiTypeAttr.java:20
(... full stacktrace at end of post)

To reproduce it:

1.) clone yeb from github
git clone git://github.com/chrisichris/yeb.git

2.) $cd yeb

3.) in the yeb dir:
$java -jar ybuilder.jar clean, compile // to compile yeb
$java -jar ybuilder.jar -yeti // to start the repl with all
dependencies

>load org.yeb.mongo //throws exception

Sorry for this lengthy procedure but I can not reproduce it otherwise.

Chris

BTW this "bug" was no bug it was due to I having an empty struct {} and thanks to Madis the compiler checks now for that.
