JNI Debugging

If you are a Java developer working with JNI code, debugging it can be particularly hard, for example if you are experiencing an unexpected SIGSEGV and don't know why.
There are several techniques which we can use to try and help get to the bottom of these:
If the JVM crashes whilst executing our native C++ code via JNI, then it will typically write a crash report to a file named like hs_err_pid76448.log in the same location that the java process was launched from.
Such a hs_err crash report might look like:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007fff87283132, pid=76448, tid=5891
#
# JRE version: Java(TM) SE Runtime Environment (7.0_80-b15) (build 1.7.0_80-b15)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (24.80-b11 mixed mode bsd-amd64 compressed oops)
# Problematic frame:
# C [libsystem_c.dylib+0x1132] strlen+0x12
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
#
# If you would like to submit a bug report, please visit:
# http://bugreport.java.com/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

** TODO **
ASAN (Google Address Sanitizer) attempts to detect a whole range of memory and range issues and can be compiled into your code, at runtime, it will report some memory or buffer-range violations.
-
Set JDK 7 as required by RocksJava
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home -
Ensure a clean start:
make clean jclean
-
Compile the Java test suite with ASAN compiled in:
DEBUG_LEVEL=2 COMPILE_WITH_ASAN=true make jtest_compile
-
Execute the entire Java Test Suite:
make jtest_run
or for a single test (e.g.
ComparatorTest), execute:cd java java -ea -Xcheck:jni -Djava.library.path=target -cp "target/classes:target/test-classes:test-libs/junit-4.12.jar:test-libs/hamcrest-core-1.3.jar:test-libs/mockito-all-1.10.19.jar:test-libs/cglib-2.2.2.jar:test-libs/assertj-core-1.7.1.jar:target/*" org.rocksdb.test.RocksJunitRunner org.rocksdb.ComparatorTest```
If ASAN detects an issue, you will see output similar to the following:
Run: org.rocksdb.BackupableDBOptionsTest testing now -> destroyOldData
Run: org.rocksdb.BackupEngineTest testing now -> deleteBackup

The output from ASAN shows a stack-trace with file names and line numbers of our C++ code that led to the issue, hopefully this helps shed some light on where the issue is occurring and perhaps why.
Unfortunately all of those (<unknown module>) are execution paths inside the JVM, ASAN cannot discover them because the JVM we are using was not itself build with support for ASAN. We could attempt to build our own JVM from the OpenJDK project and include ASAN, but at the moment that process for Mac OS X seems to be broken: https://github.com/hgomez/obuildfactory/issues/51.
** TODO ** Note the path of the DSO for libasan on Mac OS X: /Library/Developer/CommandLineTools/usr/lib/clang/7.3.0/lib/darwin/libclang_rt.asan_osx_dynamic.dylib
-
Set JDK 7 as required by RocksJava
export JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk" export PATH="${PATH}:${JAVA_HOME}/bin"
You might also need to run
sudo alternatives --config javaand select OpenJDK 7. -
Perform a clean build where ASAN is compiled in (from your RocksDB folder):
