Description

I have a particular eml message which appears to cause a complete memory overflow deep within commons-email.
A look at the source code does reveal a suspect "while" loop which appears to never exit properly, and should be rewritten so that bad data could not give us this situation.
The stack trace is :
java.lang.OutOfMemoryError: Java heap space

There are many public threads illustrating this same error, but they never pinpoint the code to Commons Email, I'm guessing I'm using the code in a way which exhibits this behaviour :
