Exception stack trace
When using APR for a connector and trying to bind to an ipv6 address (other
than lo ::1 or all ::), the connector fails to initialize with a "[22] Invalid
argument" exception. I'm using the default server.xml with the address
attribute added on the Connectors to reproduce. I noticed that the error is
coming up from the Socket.bind() call, but I wanted to open this with the
AprEndpoint in mind because it isn't crashing in the natives. Also note that I
am using OpenJDK 8u77 for my testing.
This only occurs with APR (NIO/NIO2 seem OK). I'm testing with APR 1.5.2 and
OpenSSL 1.0.2g:
07-Apr-2016 12:02:28.415 INFO [main]
org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded APR based
Apache Tomcat Native library 1.2.6 using APR version 1.5.2.
07-Apr-2016 12:02:28.415 INFO [main]
org.apache.catalina.core.AprLifecycleListener.lifecycleEvent APR capabilities:
IPv6 [true], sendfile [true], accept filters [false], random [true].
07-Apr-2016 12:02:28.417 INFO [main]
org.apache.catalina.core.AprLifecycleListener.initializeSSL OpenSSL
successfully initialized (OpenSSL 1.0.2g-fips 1 Mar 2016)
I put a breakpoint on the bind call, but the working (lo) bind and the
non-working one look pretty much identical. I am not familiar with
network/socket programming, so it's pretty foreign to me.
This does occur on tomcat-trunk as well.
