Nathan Howell created MESOS-1056:
------------------------------------
Summary: JNI wrapper does not check for exceptions
Key: MESOS-1056
URL: https://issues.apache.org/jira/browse/MESOS-1056
Project: Mesos
Issue Type: Bug
Components: java api
Affects Versions: 0.16.0
Reporter: Nathan Howell
Priority: Minor
If you run a Java framework built against Protocol Buffers 2.5.0 but compiled
Mesos against 2.4.1 it will cause segfault in jni_GetByteArrayElements.
This is triggered if org.apache.mesos.Protos.FrameworkInfo.toByteArray throws
an exception, which is (unfortunately) by-design according to
https://code.google.com/p/protobuf/issues/detail?id=493. The JNI wrapper, most
notably construct<FrameworkInfo>(...), does not check if an
env->ExceptionOccurred after invoking FrameworkInfo.toByteArray and this angers
the JVM.
