Hi, Using HttpClient 4.5.10, and with a small modification to QuickStart.java to download the 3GB ZIP archive from https://ipt.artsdatabanken.no/archive.do?r=speciesobservationsservice2 , I see an exception when running under Java 8, but success when running under Java 11.
$ /usr/lib/jvm/java-8-openjdk-amd64/bin/java -classpath .:httpcore-4.4.12.jar:commons-logging-1.2.jar:commons-codec-1.11.jar org.apache.http.client.examples.QuickStart HTTP/1.1 200 Exception in thread "main" org.apache.http.TruncatedChunkException: Truncated chunk (expected size: 16,368; actual size: 12,147) at org.apache.http.impl.io.ChunkedInputStream.read(ChunkedInputStream.java:197) at org.apache.http.impl.io.ChunkedInputStream.read(ChunkedInputStream.java:210) at org.apache.http.impl.io.ChunkedInputStream.close(ChunkedInputStream.java:312) at org.apache.http.impl.execchain.ResponseEntityProxy.streamClosed(ResponseEntityProxy.java:142) at org.apache.http.conn.EofSensorInputStream.checkClose(EofSensorInputStream.java:228) at org.apache.http.conn.EofSensorInputStream.close(EofSensorInputStream.java:172) at org.apache.http.util.EntityUtils.consume(EntityUtils.java:90) at org.apache.http.client.examples.QuickStart.main(QuickStart.java:62) The exception consistently occurs when around 1GB has been downloaded (the issue was discovered using entity.writeTo(fileOutputStream)), but the exact amount can differ by a few kB. $ /usr/lib/jvm/java-11-openjdk-amd64/bin/java -classpath .:httpcore-4.4.12.jar:commons-logging-1.2.jar:commons-codec-1.11.jar org.apache.http.client.examples.QuickStart HTTP/1.1 200 I'm also able to download the file without a problem using Curl, Wget, Firefox and so on, so this seems like a problem in either HttpComponents or Java 8. Does anyone have any ideas on what might be causing the problem? In case it's relevant, a download using Java 11 (or Curl or Wget) runs at just over 800-900Mb/s, and the Java 8 download at 150Mbit/s. Using Wireshark, I see a TLS "Encrypted Alert" packet is received when using Java 8, but I don't really know what this means.
