-------------------------------------------
Summary: CloseableHttpClient.execute generates SIGSEGV in jvm
Key: HTTPCLIENT-1812
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1812
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.2, 4.5.3
Environment: openjdk version "1.8.0_121"
OpenJDK Runtime Environment (IcedTea 3.3.0) (suse-6.4-x86_64)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
Reporter: Harald Brennich
Attachments: hs_error.log
I am using HttpComponents to read a specific web page. This worked fine until
yesterday (02/03/2017). Now, on executing a request to the URI
http://www.timeanddate.com/astronomy/germany/munich, the JVM reports a SIGSEGV.
See attachment.for version 4.53. Version 4.5.2 was similar.
On slightly modifying the calling java code by instantiating the
HttpClientBuilder before building the CloseableHttpClient, instead of
sigsegving an exception is thrown:

Finally, on setting the user agent (via HttpClientBuilder.setUserAgent) to
"Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0" the
CloseableHttpClient.execute works again (as it did previously)
