I came across this confusing error using the Smack API:
java.io.EOFException: no more data available - expected end tag </stream:stream> to close start tag <stream:stream> from line 1, parser stopped on END_TAG seen ...EZah/08YglY=\' xmlns=\'http://jabber.org/protocol/caps\'/></presence>... @1:2797 at org.xmlpull.mxp1.MXParser.fillBuf(MXParser.java:3035) at org.xmlpull.mxp1.MXParser.more(MXParser.java:3046) at org.xmlpull.mxp1.MXParser.nextImpl(MXParser.java:1144) at org.xmlpull.mxp1.MXParser.next(MXParser.java:1093) at org.jivesoftware.smack.PacketReader.parsePackets(PacketReader.java:36
Turns out this was because I was trying to send a message containing the string “ ”.
I was pulling data from an xml document, that unfortunately rather than containing nothing where there was no entry for an element, contained four “ ”.
It seems even trying to pass one makes Smack throw a major wobbly.
Figuring out the error took ages. Fixing was easy as I just stripped out all “ ” characters.
EDIT: It’s ampersands in general that causes the problem (makes more sense really). What’s more, I can’t figure out a way to catch the “java.io.EOFException”. I get “never thrown in body of corresponding try statement” if I try (no pun intended!) to catch it where the Bot is connecting. So I don’t think anything can be done apart form make sure you are never passing Ampersands via Smack.
