svyUtil 1.4.1, svyIO.zip(): java.util.zip.ZipException

Feedback

Switched to Servoy 2020.03 and svyUtil 1.4.1 from Servoy 2019.12.1 and svyUtil 1.3.1. Java version 1.8.0_212 x64.
I’m using svyIO.zip() to create a zip file of PDFs. In the new 1.4.1 I get the following exception:

ERROR com.servoy.j2db.util.Debug - ERROR Error zipping file "C:\Servoy_Files\2020-4-9_13-47-11": java.util.zip.ZipException: no current ZIP entry

The exception occurs on the line ```
dest.write(buffer);

function channelCopy(src, dest) {
var buffer = java.nio.ByteBuffer.allocateDirect(16 * 1024);
while (src.read(buffer) != -1) {
// prepare the buffer to be drained
buffer.flip();
// write to the channel, may block
dest.write(buffer);
// If partial transfer, shift remainder down
// If buffer is empty, same as doing clear()
buffer.compact();
}
// EOF will leave buffer in fill state
buffer.flip();
// make sure the buffer is fully drained.
while (buffer.hasRemaining()) {
dest.write(buffer);
}
src.close();
}


Tested svyUtil 1.3.1 svyIO.zip() with Servoy 2020.03 and it works fine.
I could not find any requirements on java version needed.
Any idea on why this fails?
Thanks,

I have fixed that now in master.

Please comment out line 230 in svyIO like this:

// zipOutputStream.closeEntry();

That should fix the problem until the next version is released.

That worked.
Thanks,
