Out of memory with java sdk during uploading (unlimited upload buffer)
Hi,
I'm tring to use the java sdk to move file from pc to dropbox space.
I've written a method that upload file without problem while they are sufficently small (50MB), but generate a java.lang.OutOfMemoryError: Java heap space when the file is bigger
This is the trace thati I obtain
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2271) at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:118) at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:153) at sun.net.www.http.PosterOutputStream.write(PosterOutputStream.java:78) at com.dropbox.core.util.IOUtil.copyStreamToStream(IOUtil.java:59) at com.dropbox.core.util.IOUtil.copyStreamToStream(IOUtil.java:68) at com.dropbox.core.util.IOUtil.copyStreamToStream(IOUtil.java:43) at com.dropbox.core.http.HttpRequestor$Uploader.upload(HttpRequestor.java:98) at com.dropbox.core.DbxUploader.uploadAndFinish(DbxUploader.java:95) at com.dropbox.core.v2.DbxUploadStyleBuilder.uploadAndFinish(DbxUploadStyleBuilder.java:92) at it.xxx.cloudLib.CopyToDropBox.upload(CopyToDropBox.java:45)
Is there the possibiliy to configure the library buffer?
Thank for your help

Thanks for the report! I don't believe the buffer is configurable, but we'll be happy to look into this issue.
First, what version of the SDK are you using? If you're not already using the latest version (currently v3.0.3) please update to that and try again.
If you're still seeing this issue on the latest version, please let me know, and share the code to reproduce the issue. Thanks in advance!Hi Greg,
you can find a sample project that show the same problem here

I'm using the last SDK version as you can find in the pom.
During my test I have experienced the same issue using one of 2.x.x version
I'm experiencing the problem using
Linux XXX 3.2.0-126-generic #169-Ubuntu SMP Fri Mar 31 14:15:21 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
I'm compiling for 1.7 versionI obtain the error trying to uploading a file of 1.1 GB, I know that the maximum size for a file is 5GB, do I hope I can use the SDK till this line
Thanks for your help
