Could not copy slave.jar into ... on slave

XMLWordPrintable

      Since one of the last updates I cannot connect a slave, which is running a different java version. Jenkins is version 1.558 with Oracle Java 1.7.0_51 and the slave is an x86 box using OpenJDK 1.6.0_27. It is impossible to switch to another Java version on the node. If I try to establish the connection, it fails with this output:

      The connection itself is opened successfully and if I put slave.jar from another node onto this one, it get's deleted during the above steps. But then scp fails!? Any ideas?

      The connection to another node with the same OpenJDK version but x86_64 architecture works without any problems.
