'String index out of range: -1' error when creating a new entity

[kvamer]

Hi. Does anybody know how to create entities with BO in the end?
I want to create a new entity FactBO. When I type 'entity --name ~.model.FactBO' I get the following message from Roo:

Created SRC_MAIN_JAVA ... FactBO.java
Undo create SRC_MAIN_JAVA ... FactBO.java
String index out of range: -1.

When I try to create FactBo with a small 'o' in the end everything works fine. It also works if I type 'entity --name ~.model.SomethingBO'. It seems there's a bug somewhere and Roo cannot create some entities with BO in the end.

Hmm that is certainly weird behaviour. Can you please open a Jira ticket for this so we can take a closer look?

Thanks!

Appears to be due to an Inflector bug:

roo> entity --name ~.foo.BarBO
Created SRC_MAIN_JAVA/com/foo/foo
Created SRC_MAIN_JAVA/com/foo/foo/BarBO.java
Undo create SRC_MAIN_JAVA/com/foo/foo/BarBO.java
Undo create SRC_MAIN_JAVA/com/foo/foo
String index out of range: -1

We should catch this bug and try again with a lowercase conversion.
