*Root cause:*
`PlannerModule` uses a URLClassloader to load class and has an exceptional list
to load owner owned classes:
{code:java}
class PlannerModule {
/**
* The name of the table planner dependency jar, bundled with
flink-table-planner-loader module
* artifact.
*/
static final String FLINK_TABLE_PLANNER_FAT_JAR = "flink-table-planner.jar";
private static final String HINT_USAGE =
"mvn clean package -pl
flink-table/flink-table-planner,flink-table/flink-table-planner-loader
-DskipTests";
private static final String[] OWNER_CLASSPATH =
Stream.concat(
Arrays.stream(CoreOptions.PARENT_FIRST_LOGGING_PATTERNS),
Stream.of(
// These packages are shipped either by
// flink-table-runtime or flink-dist itself
"org.codehaus.janino",
"org.codehaus.commons",
"org.apache.commons.lang3",
"org.apache.commons.math3",
// with hive dialect, hadoop jar should be
in classpath,
// also, we should make it loaded by owner
classloader,
// otherwise, it'll throw class not found
exception
// when initialize HiveParser which
requires hadoop
"org.apache.hadoop"))
.toArray(String[]::new); {code}
But the group of `org.apache.commons.text` is not on the list.
*Fix:*
Add `org.apache.commons.text` to the list
