Mario Ivankovits resolved VFS-107.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.1
ok, I've changed VFS head now to use the stream based methods, the test cases
still work, so it looks like it works now.
Thanks!
Ciao,

> large Sftp transfers fail with OutOfMemoryError: Java heap space
> ----------------------------------------------------------------
>
> Key: VFS-107
> URL: https://issues.apache.org/jira/browse/VFS-107
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: Nightly Builds
> Environment: java version "1.5.0_04"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
> Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)
> Linux version 2.6.17-1.2142_FC4 ([EMAIL PROTECTED]) (gcc version 4.0.2
> 20051125 (Red Hat 4.0.2-8)) #1 Tue Jul 11 22:41:14 EDT 2006
> Reporter: Marty Lamb
> Fix For: 1.1
>
> Attachments: SftpFileObject.java
>
>
> Calling SftpFileObject.getOutputStream() returns a descendant of
> ByteArrayOutputStream; nothing is written to the remote sftp server until the
> OutputStream is closed. For large data transfers, this exhausts local
> resources.
> This is noted in the source for SftpFileObject:
> protected OutputStream doGetOutputStream(boolean bAppend) throws
> Exception
> {
> // TODO - Don't write the entire file into memory. Use the
> stream-based
> // methods on ChannelSftp once the work properly
> final ChannelSftp channel = fileSystem.getChannel();
> return new SftpOutputStream(channel);
> }
> although it is not clear what "once the[y] work properly" is referring to.
