      Description



      Name: szR10032 Date: 09/18/2000



      The nsk/logging/FileHandler/FileHandler/flhndlr001 test uses
        java.util.logging.FileHandler.pattern = flhndlr001.%g.log
        java.util.logging.FileHandler.limit = 20
        java.util.logging.FileHandler.count = 3
      properties and produces 10 ten-byte log records in one thread.
      The test expects this to result in exactly 3 log files (flhndlr001.0.log,
      flhndlr001.1.log, flhndlr001.2.log) of 20 bytes length each according to used
      properties. However, 4 log files (flhndlr001.0.log, flhndlr001.0.log.1,
      flhndlr001.1.log.1, flhndlr001.2.log.1) are created.
      Moreover, flhndlr001.0.log and flhndlr001.0.log.1 files have no info
      after the test end so that 2 messages are lost.

      Such implementation behavior is not specified by the spec
      and is not desired.

      See log, source and logging.properties file below.
