SBLIM JSR48 CIM Client 2.2.3

Today the SBLIM project has released the JSR48 CIM Client for Java version 2.2.3. It contains several new features:

  • A new Java property - sblim.wbem.listenerMaxQueuedEvents - can be used to set the maximum number of queued events awaiting dispatch to a listener. (#2628)
  • Two new Java properties - sblim.wbem.listenerHttpHeaderTimeout and sblim.wbem.listenerHttpMaxAllowedTimeouts - can be used to help prevent Denial of Service attacks on an indication listener via the slowloris approach (#2635)
  • Two new private APIs - WBEMListenerSBLIM.getBlockedIPs and setBlockedIPs can be used to control the IPs of incoming connections that are to be ignored by an indication listener (#2635)
  • Two new Java properties - sblim.wbem.sslClientCipherSuitesToDisable and sblim.wbem.sslListenerCipherSuitesToDisable - can be used to disable a list of cipher suites when connecting via an SSL socket as either a client or listener. (#2642)

Version 2.2.3 also contains several changes that might affect existing applications:

  • The internal ChunkedInputStream constructors now require a second parameter, a String representing the names of the trailer fields (from HTTP Trailer header). (#2621)
  • The internal MessageReader constructor now requires a second parameter, a long representing the HTTP header timeout (#2635)
  • The internal HttpConnectionHandler constructor now requires a second parameter, a WBEMConfiguration representing the configuration properties (#2635)
  • The Java property sblim.wbem.sslCipherSuitesToDisable has been deleted, use sblim.wbem.sslClientCipherSuitesToDisable and/or sblim.wbem.sslListenerCipherSuitesToDisable instead (#2642)

The complete list of changes follows:
