xie tao commented on CODEC-263:
---
Codec version < 1.13, it will not throw exception. And in version 1.13
'Base64.isBase64("publishMessage")' return true.
So I think method Base64.decodeBase64() and Base64.isBase64() must has
consistent result。 code as below
{code:java}
// test result is true
if(Base64.isBase64("publishMessage")){
// throw exception
Base64.decodeBase64("publishMessage");
}
{code}
therefore, Base64.isBase64() and Base64.decodeBase64() inconsistent method
behavior.
