Try "RSA/ECB/PKCS1Padding" instead if you are running in an Oracle or Open JDK. It does not make too much sense to use a block cipher mode of encryption with RSA, but not all algorithm names are logical within the Java SE providers.

The Bouncy Castle Libraries support "RSA/None/PKCS1Padding" though. So maybe the code was written for Bouncy or Android.
