Package: openjdk-8-jre-headless
Version: 8u131-b11-2
Severity: normal

Dear Maintainer,

When running python code that calls the JVM via JNI GDB can't install the
openjdk unwinder.

When running gdb --args python -m jcc --jar some-jar-file.jar and then running
(just make a virtualenv, pip install jcc, and point it at some jar file):

Starting program: /home/joshua/unnaturalcode/venv3/bin/python -m jcc --jar
java/lex-java/target/lex-java-1.0-SNAPSHOT.jar
