  ****************************************************************
  01.The cancellable threads (Download thread and Search thread)
     are not canceled by RDz "Cancel User" command.
  02.Dataset lock is not released when the client is canceled by
     RDz client or RDz console command.
  03.Java Out Of Memory occurred in Search request.
  04.File Lock is not released owing to NullPointerException in
     finish() method in MVSminer.
  05.When a thread is aborted, the thread must be a user thread
     for zOS to release the lock-related resources.
  06.There is a case where RDz client initiates file updates but
     it does not upload any data for the updates. In closing the
     file output stream, the server tries to invoke the putFile
     API, although there is no data received.
  07.REXEC connection is not established.
  08.The non-secured thread of OpenRSE base writes a trace in the
     rsecomm.log first.
  09.File Lock is not released, and sometimes protection exception
     occurred
  10.stdout/stderr logging has no timestamp. The trace entries in
     stdout/stderr cannot be mapped to other traces.
  11.Java Out Of Memory occurred.
  12.RDz receives FEK105E Error in sending audit data (rc=EOTHER)
     in z/OS system log as RSE failed to update the audit.log
  13.The concurrent thread exception occurred in MVS miner
     finish() method.
  14.When the data set whose block size is 0 is read in readFile()
     ABENDS002 occurs in libfekfmain.so in ffsjni call.
  15.The dataset is not closed when the record format is "U".
  16.When running PassTicket IVP, there is no explanation about
     the SAF API which issued the error codes.
  17.enhancement: add support for debugging JVM startup problems
     /usr/lpp/rdz/bin/debug.JVMstartup
  18.Downloaded zip file name is not correct when
     C_GET_MEMBER_COPYBOOK is used to get a member without an
     extension
  19.JVM OutOfMemory occurred in downloading a big file.
  20.Request timed out error logged on client side and 0C4 found
     in rsecomm.log when running 2 remote z/OS searches
  21.Open RSE base defines C_SEND_INPUT as broadcast command and
     will send it to all of the miners.
  22.The RSEDENV (rsed.envvars) file is truncated due to the
     special character < incorrectly handled at generation in the
     skeleton FEKRSEDE.
  23.Get VSAM data set attribute fails.
  

Problem conclusion

• 01.Now, RDz "Cancel User" command will cancel the cancellable
     threads.
  02.Now, the locked resources are explicitly released (unlocked)
     when the client is canceled.
  03.Now, MVS miner will check the size of the free heaps in a
     timely manner according to the Search activities and break
     the Search process.
  04.NullPointerException occurred in fetching the system name.
     Now, MVSminer will check whether it could fetch the system
     name.
  05.Now, the thread with a lock will issue pthread_security_np
     to make the thread a user thread.
  06.Now, RDz does not invoke the putFile API when there is no
     data received.
  07.In REXEC connection, RDz server must not use daemon-unique
     class but in another fix the daemon-unique class is referred
     to. Now, this class will not be referred to in the REXEC
     connection.
  08.Now, the threadpool server writes a trace in the rsecomm.log
     before other server threads writes traces.
  09.The thread which holds the file locks has a table to store
     the locked resources, but the table is damaged owing to a bad
     logic. Now, the logic to manage the locks is corrected.
  10.Now, each stdout/stderr logging entry has timestamp.
  11.Now, MVS miner will check the size of the free heaps in a
     timely manner according to the activities and invoke JVM
     garbage collection.
  12.rc=EOTHER means that other code was returned by send API.
     In fact, the return code was EMSGSIZE (Message too long).
     MVSminer tried to write a big data for nonroundtrippable
     characters.
     Now, RDz will truncate the audit log data to 256 bytes
  13.Now, the concurrent thread exception will not occur in
     MVS miner finish() method.
  14.Server side
     - Add check the block size of the selected data set in
       readFile() routine on server side. If the block size is 0,
       it just returns before executing read.
     Client side
     - When the menu Open, View or Browse is selected for the data
       set and the block size is 0, the error message appears.
       "Could not read a remote file that has invalid block size."
     - Provide this error message in both Remote Systems view and
       Enterprise project view.
  15.Now, the dataset is closed even if the record format is "U".
  16.There is a design problem that RACF java API is invoked to
     generate a passticket before invoking the PassTickt IVP.
     Now, the RACF java API is not invoked when running the
     PassTicket IVP.
     And API information is added to an error message.
  17.enhancement: add support for debugging JVM startup problems
     /usr/lpp/rdz/bin/debug.JVMstartup
  18.".zip" is added to the zip file name, when the downloaded
     copy member was created on server.
  19.When RDz server downloads a big file, the big file will be
     divided into the client-specified buffer size and each piece
     by buffer size will be downloaded.
     Now, RDz server will check the remaining JVM heap size every
     time each piece is downloaded, and RDz server will stop
     downloading and return the corresponding code to RDz client
     when JVM is near short of its heap.
  20.The code conversion is changed to Java codes from C codes in
     MVSByteConverter.getClientCharForNotSymbol() method, because
     abends occured in C codes.
  21.Now, C_SEND_INPUT commnad is defined as a specific command
     for CommandMiner only.
  22.The skeleton FEKRSEDE has been modified to handle the
     characters < > and prevent truncation.
  23.The check is added before the methods of JZOS are called.
