            Bug ID: 2397
           Summary: 64-bit VM hangs and fails to respond to any signal
           Product: IcedTea
           Version: unspecified
          Hardware: 64-bit
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: IcedTea
          Assignee: gnu.andrew at redhat.com
          Reporter: ixyene at gmail.com
                CC: unassigned at icedtea.classpath.org

On our 64-bit 1.7.0_79 server VM, a user-submitted piece of code causes the VM
to hang and subsequently fail to respond to any signal (SIGTERM et al.) This is
reproducible on multiple machines.

java -version:
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

uname -a:
Linux astatine 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24)
x86_64 GNU/Linux

I've been able to reproduce this issue on multiple machines running the most
recent Java 7u79. Approximately 30-40 minutes after the VM stops responding,
the VM exits and writes a diagnostic info file.

Reproduction:

https://gist.github.com/anonymous/fa1ff9bf55022030919b (input data that the
above program should read from stdin)

I'm running the JVM with no non-standard flags.
