--------------------------------------
Summary: Not support sun.util.calendar.ZoneInfo in java 17
Key: SPARK-51515
URL: https://issues.apache.org/jira/browse/SPARK-51515
Project: Spark
Issue Type: Bug
Components: Build, Tests
Affects Versions: 4.0.0
Reporter: dong hwan jung
During test "DateExpressionsSuite" in sql/catalyst.. I met the below error
{code:java}
symbolic reference class is not accessible: class sun.util.calendar.ZoneInfo,
from interface org.apache.spark.sql.catalyst.util.SparkDateTimeUtils (unnamed
module @12b0404f)java.lang.IllegalAccessException: symbolic reference class is
not accessible: class sun.util.calendar.ZoneInfo, from interface
org.apache.spark.sql.catalyst.util.SparkDateTimeUtils (unnamed module
@12b0404f) at
java.base/java.lang.invoke.MemberName.makeAccessException(MemberName.java:955)

java.base/java.lang.invoke.MethodHandles$Lookup.checkSymbolicClass(MethodHandles.java:3686)

java.base/java.lang.invoke.MethodHandles$Lookup.resolveOrFail(MethodHandles.java:3646)
at
java.base/java.lang.invoke.MethodHandles$Lookup.findVirtual(MethodHandles.java:2680)
{code}
So, I failed 3 tests: DateFormat, unix_timestamp, to_unix_timestamp
As I know, since spark 4.x, java 17 would be used by default.
Java 17 cannot use "sun.*" API by default, we need to replace all apis in the
spark code.
