clearReferences系のエラーログ、その2

clearReferencesJdbcは Seasar2 の DriverManagerUtil#deregisterAllDrivers() で無事に削除できた。でも、まだ、clearReferencesThreadsとclearThreadLocalMapがでますね…。clearReferencesThreadsの方は終了するときにsleepをしたりすると、でなくなったりするので、スレッドの終了待ちをすれば良いのかも。clearThreadLocalMapは自分でnullにしないといかんのか? この問題って、ぐぐっても Jackrabbit くらいしか引っかからんのだけど、まだ Tomcat 6.0.24 ってあまりつかわれていないのだろうか…。
