Subject [jira] [Created] (HTTPCLIENT-1812) CloseableHttpClient.execute generates SIGSEGV in jvm
Date Sat, 04 Feb 2017 10:00:57 GMT
Harald Brennich created HTTPCLIENT-1812:
-------------------------------------------

             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)
