[jira] Created: (FTPSERVER-114) File locks when running on IBM:s JVM

File locks when running on IBM:s JVM
------------------------------------

                 Key: FTPSERVER-114
                 URL: https://issues.apache.org/jira/browse/FTPSERVER-114
             Project: FtpServer
          Issue Type: Bug
          Components: Core
         Environment: java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pwi32devifx-20070608 (SR5+IY99712))
IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32 j9vmwi3223-20070426 (JIT enabled)
J9VM - 20070420_12448_lHdSMR
JIT  - 20070419_1806_r8
GC   - 200704_19)
JCL  - 20070608

            Reporter: Magnus Grimsell


The method close on a FileOutputStream originating from a RandomAccessFile behaves differently on SUN:s and IBM:s JVM. SUN:s JVM closes the underlying RandomAccessFile and no locks remains on the file. For IBM:s JVM an explicit close on the RandomAccessFile is necessary to avoid file locks.
