JRockit 8.1 SP2 - throws java.lang.ArrayStoreException - CR134874 (Doc ID 775112.1)

Last updated on OCTOBER 31, 2018

Applies to:

Oracle JRockit / JRockit / 8.1
Information in this document applies to any platform


Customer has sent a reproducer, which produces the following exception:

Error 500--Internal Server Error

java.lang.ArrayStoreException: Object and inner type of array differs

Customer is running JRockit 8.1 SP2 on Windows 2000 Pro. Problem has been confirmed with various JVMs (see NOTES
below), and may occur on other platforms as well?

1) The exception is thrown only when the customer code tries to store inside an Array an object from a class hierarchy
of 9 levels or more.  8 levels of hierarchy work fine.  Unfortunately customer's code has a hierarchy of 11 levels so
currently they cannot run their code in JRockit.

2) They are using multiple class loaders: Some of the classes are loaded from the classpath, and some from inside a
web application.

3) I have confirmed that the problem exists in the following versions of JRockit:
  - 8.1 SP2
  - 8.1 SP2 RP1
  - 8.1 SP3 load 4 (pre-release) and earlier

4) I have confirmed that the problem does not exist in the following JVMs:
  - Sun 1.4.1_03
  - Sun 1.4.2_02
  - JRockit 8.1 SP3 load 5 (pre-release) and later

JRockit 8.1 SP2
32-bit Windows
