eBugs in Cloud Systems updated CASSANDRA-15118:
-----------------------------------------------
Description:
Dear Cassandra developers, we are developing a tool to detect exception-related
bugs in Java. Our prototype has spotted the following {{throw}} statement whose
exception class and error message seem to indicate different error conditions.
Version: Cassandra-3.11 (commit: 123113f7b887370a248669ee0db6fdf13df0146e)
File: CASSANDRA-ROOT/src/java/org/apache/cassandra/utils/obs/OffHeapBitSet.java
Line: 49
{code:java}
throw new RuntimeException("Out of native memory occured, You can avoid it by
increasing the system ram space or by increasing
bloom_filter_fp_chance.");{code}
{{RuntimeException}} is usually used to represent errors in the program logic
(think of one of its subclasses, {{NullPointerException}}), while the error
message indicates that {{OffHeapBitSet()}} ran out of memory. This mismatch
could be a problem. For example, the callers may miss the possibility that
{{OffHeapBitSet()}} can run out of memory. Or, the callers trying to handle
other {{RuntimeException}} may accidentally (and incorrectly) handle the out of
memory scenario.

{{RuntimeException}} is usually used to represent errors in the program logic

message indicates that {{OffHeapBitSet()}} ran out of memory. Will this
mismatch be a problem? For example, the callers may miss the possibility that
{{OffHeapBitSet()}} can run out of memory. Or, the callers trying to handle
other {{RuntimeException}} may accidentally (and incorrectly) handle the out of
