error when calling ts-java

[Pii Smith]

When I call ts-java (Which was quite some work to install on my windows machine) I get the following error:

$ ts-java
ts-java version 1.4.0
TypeError: Cannot read property 'size' of undefined

Anybody knows what going wrong here? I tried to change the tsjava part in my package.json, but still I always get the same error. Any tip would be appreciated.
