[pkg-j2se-devel] Re: j2re1.4: send ItemEvent without user action

[David Herron]

First, I don't think this has anything to do with packaging Java for 
Debian systems.

Second, what you're describing certainly sounds like a bug.  The 
java.awt.Choice and ItemEvent classes aren't supposed to be sent for an 
"add" operation.

You should take this to the vendor in question ... e.g. you said 
Blackdown's Java went into an infinite loop?  For a bug with Blackdown's 
Java package you should approach them.
