Abstract
WorkArea Service causes a java.lang.ArrayIndexOutOfBoundsException
 
Download Description
PQ92289 resolves the following problem:

USERS AFFECTED:
Users of the Work Area service in WebSphere Application Server v5.0 releases.

PROBLEM DESCRIPTION:
The WorkArea Service causes a java.lang.ArrayIndexOutOfBoundsException whenever an application calls many J2EE components sequentially (for example servlet chaining).

RECOMMENDATION:
The WorkArea Service causes a java.lang.ArrayIndexOutOfBoundsException whenever an application calls many J2EE components sequentially. For example, if an application calls an EJB™, which in turn calls another EJB, which in turn calls another EJB, and so on, at a certain point the array the WorkArea service uses to store this call path information can reach the array bounds. Normally, WorkArea would increment the array bounds once the maximum bound is reached. However, if the depth of the call chain ends at exactly the array bounds, a problem in the WorkArea code does not allow for the array bounds checking, causing a java.lang.ArrayIndexOutOfBoundsException as the call chain returns. Although this scenario is not common, it is not entirely impossible.

PROBLEM CONCLUSION:
The code causing the java.lang.ArrayIndexOutOfBoundsExceptionthe Work Area service when it makes successive calls to J2EE components has been fixed.
