-------------------------------------
Summary: Adapt to changes in HttpClient 5.6
Key: AXIS2-6101
URL: https://issues.apache.org/jira/browse/AXIS2-6101
Project: Axis2
Issue Type: Bug
Reporter: Chris Sorenson
Steps to reproduce:
1. Use Axis2 2.0.0 with httpclient5 5.6+
2. Make a request to a server that returns gzip-encoded responses
3. Observe "Not in GZIP format" error
Expected behavior:
Response should be properly decoded and parsed.
Actual behavior:
Axis2 attempts to decompress already-decompressed content, causing error.
Root cause:
Starting with httpclient5 5.6, the ContentCompressionExec [no longer removes
Content-Encoding
headers|https://github.com/apache/httpcomponents-client/commit/56122fd33fb8a67d23369a81f6e1d89aabf4ba10]
from the response after decompression. Axis2's
HTTPSender sees the header and tries to decompress again, causing the error.
Suggested fix:
Similar to Spring Web Services fix ([commit
4ab0ef4|https://github.com/spring-projects/spring-ws/commit/4ab0ef4af6d5bbcd5a7f41da0d5f49ca12f0e749]),
Axis2 should check the
HttpEntity's content encoding rather than relying on response headers.
