Last updated on APRIL 12, 2024
Applies to:
Oracle Containers for J2EE - Version 10.1.3.1.0 to 10.1.3.2.0 [Release AS10gR3]Information in this document applies to any platform.
Symptoms
Using JDK 1.4 and JDK 1.5 with OC4J 10.1.3.1 or 10.1.3.2 leads to different results:
There is a different behavior of the Thread Context ClassLoader with different versions of JDK.
With JDk 1.5, Thread Context ClassLoader (received from Thread.currentThread().getContextClassLoader()) in all threads is the same ClassLoader instance as the current ClassLoader (received from getClass().getClassLoader()).
With JDK 1.4, Thread Context ClassLoader (in the threads, created by application) is NOT the same ClassLoader instance as the current ClassLoader. It is even the instance of a different Class.
