The jar you're using to access CurrencyCore's API is a bit outdated.

The method "void AccountManager.removeAccount(String string)" was deprecated in 0.5 and in 0.6 removed. The replacement is "void AccountManager.deleteAccount(String string)".

Along with this at 0.7, "String[] AccountManager.getAccounts()" went deprecated and replaced with "List AccountManager.getAccountList()".

Just a heads up.

In the future please reroute deprecated methods to the new method rather than completely removing them and just tagging them as deprecated. Breaking the API in the way you've done seems mostly unnecessary as the methods use identical arguments, or just change the base functionality of the method as the only change seems like it was internal.

Thanks for adding a List return on the accounts.
