It seems to be a duplicate of issue 257800,
which describes a classical deadlock within jsch.

The jsch code takes locks 0x00000000df6782c0 and 0x00000000df6782a0 
in different order.

"AWT-EventQueue-0":
	at java.util.Vector.removeAllElements(Vector.java:656)
	- waiting to lock <0x00000000df6782c0> (a java.util.Vector)
	at com.jcraft.jsch.KnownHosts.setKnownHosts(KnownHosts.java:61)
	at com.jcraft.jsch.KnownHosts.setKnownHosts(KnownHosts.java:54)
	at com.jcraft.jsch.JSch.setKnownHosts(JSch.java:317)
	- locked <0x00000000df6782a0> (a com.jcraft.jsch.KnownHosts)

"Initializing path map at hudson@spb-ladoga.ru.oracle.com":
	at com.jcraft.jsch.KnownHosts.getHMACSHA1(KnownHosts.java:486)
	- waiting to lock <0x00000000df6782a0> (a com.jcraft.jsch.KnownHosts)
	at com.jcraft.jsch.KnownHosts.access$000(KnownHosts.java:35)
	at com.jcraft.jsch.KnownHosts$HashedHostKey.isMatched(KnownHosts.java:540)
	at com.jcraft.jsch.KnownHosts.getHostKey(KnownHosts.java:361)
	- locked <0x00000000df6782c0> (a java.util.Vector)
	at com.jcraft.jsch.Session.checkHost(Session.java:809)
	at com.jcraft.jsch.Session.connect(Session.java:342)

Frankly, I don't know what to do with that. I wrote to jsch alias and the only reply was from the other user, who faced the same problem and proposed a patch.. and silence.
