IMPALA-12102: Avoid memory leaks in the handling of JNI exceptions
During the processing of JNI Exceptions, some local references
were not released in a timely manner, which may lead to memory
leaks in the JVM.
Testing:
- Manually verified that the memory leak doesn't occur in the
local development environment.
