postgresql jdbcドライバ 9.4.1212 をjdk11で使用すると 'WARNING: An illegal reflective access operation has occurred'が出力される

Last updated at Posted at 2020-04-25

postgresql jdbcドライバ 9.4.1212 をjdk11で使用すると

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.postgresql.jdbc.TimestampUtils (file:/XXX) to field java.util.TimeZone.defaultTimeZone
WARNING: Please consider reporting this to the maintainers of org.postgresql.jdbc.TimestampUtils
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations

と出力されます。

これは、jdk9以上で、保護されたクラスに対して、
Field.setAccessible(true) を実行すると出力されるようです。

jdbc ドライバ 42.2.12 を使用するとこの警告は出力されません。

そこで、42.2.12 の  org.postgresql.jdbc.TimestampUtils のソースを調べてみると、
106行目に
if (JavaVersion.getRuntimeVersion().compareTo(JavaVersion.v1_8) <= 0)
とあり、後続の、Field.setAccessible(true) を回避しています。
