Pull request overview
This PR addresses potential JNI local reference table overflows/leaks in the Java ADBC JNI driver by explicitly deleting JNI local references that can otherwise accumulate during long-running native calls or loops.
Changes:
- Delete the
jstringlocal reference inJniStringView’s destructor after releasing UTF chars. - In
statementExecutePartitions, add a null/exception check afterNewByteArrayand delete the per-iterationjbyteArraylocal reference after passing it to Java.
