Thomas Pummer commented on EMAIL-110:
-------------------------------------
I've checked the RFC 822 http://www.ietf.org/rfc/rfc822.txt
In appendix B.2 it is stated that the header has to be seperated from the
content by a null line. The eml file given with this issue is missing this
seperating line.
> java.lang.OutOfMemoryError: Java heap space while parsing Mime part

> Key: EMAIL-110
> URL: https://issues.apache.org/jira/browse/EMAIL-110
> Project: Commons Email
> Issue Type: Bug
> Affects Versions: 1.2
> Environment: Windows, Linux
> Reporter: Stephen Kruger
> Assignee: Siegfried Goeschl
> Priority: Blocker
> Attachments: MailBug.zip, crashfix.eml
>
>
> 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
> at java.util.Arrays.copyOf(Arrays.java:2786)

> 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
