-------------------------------------
Summary: Unable to init Verb in jvm-dtest
Key: CASSANDRA-15383
URL: https://issues.apache.org/jira/browse/CASSANDRA-15383
Project: Cassandra
Issue Type: Bug
Components: Test/dtest
Reporter: Yifan Cai
Verb cannot be initialized in dtest. The test cases that has references to Verb
get the following error
{code:java}
java.lang.ExceptionInInitializerError
at org.apache.cassandra.net.Verb.<clinit>(Verb.java:87)
at
org.apache.cassandra.distributed.test.DistributedReadWritePathTest.failingReadRepairTest(DistributedReadWritePathTest.java:134)
Caused by: java.lang.NullPointerException
at
org.apache.cassandra.config.DatabaseDescriptor.getConcurrentReaders(DatabaseDescriptor.java:1611)
at org.apache.cassandra.concurrent.Stage.<clinit>(Stage.java:48)
{code}
It is caused by the DatabaseDescriptor being uninitialized and NPE was thrown.
The dtest initializes the DatabaseDescriptor at instance-level with the
isolated InstanceClassLoader. Since test code is not loaded by the
InstanceClassLoader, it does not know the already initialized
DatabaseDescriptor.
