Tathagata Das 49666d76cf Fix swallowing of exception in Java RocksDB when loading native library (#4728)
Summary:
This PR fixes #4721. When an exception is caught and thrown as a different exception, then the original exception should be  inserted as a cause of the new exception. This bug in RocksDB was swallowing the underlying exception from `NativeLibraryLoader` and throwing the following exception
```
...
Caused by: java.lang.RuntimeException: Unable to load the RocksDB shared libraryjava.nio.channels.ClosedByInterruptException
  at org.rocksdb.RocksDB.loadLibrary(RocksDB.java:67)
  at org.rocksdb.RocksDB.<clinit>(RocksDB.java:35)
  ... 73 more
```

The fix is simple and self-explanatory.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Linux/Mac Build Status Windows Build status PPC64le Build Status

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
