[JSch-users] Why JSch (JSCH-0.0.6) throws exception, caused by java.security.SignatureException?

[Audrius M. <Aud...@me...>]

While trying to open a connection, under Linux I sometimes get the following
exception:

java.security.SignatureException: invalid signature: out of range values
at sun.security.provider.DSA.engineVerify(DSA.java:228)
at sun.security.provider.DSA.engineVerify(DSA.java:182)
at java.security.Signature.verify(Signature.java:464)
at com.jcraft.jsch.jce.SignatureDSA.verify(SignatureDSA.java:120)
at com.jcraft.jsch.jce.DHG1.start(DHG1.java:221)
at com.jcraft.jsch.Session.connect(Session.java:204)
at Sight.util.ssh.Server.<init>(Server.java:88) (my code starts)

Strange, but this also happens only under Mandrake Linux 9.0. The problem is
transient, and it is possible just to catch that exception and retry. After
several retries, the connection finally can be created. Hence this is not a
problem of the wrong server address or wrong user information. I wrote this
workaround, and it works, but my application started to crash time to time
with 'mac error', mentioned in my previous message. Maybe these two problems
are linked somehow?
