APAR status

  • Closed as program error.

Error description

  • Error Message: An ArrayIndexOutOfBounds exception is encountered
during the execution of a Java application
.
Stack Trace: N/A
.

Local fix

  • -Xjit:disableIdiomRecognition

Problem summary

  • The optimizer replaces a loop that performs copying between
character and byte arrays into a call to a fast optimized
arraycopy helper. In this scenario, the length computed by the
optimizer is incorrect, so the helper accesses elements that are
out of bounds of the arrays.

Problem conclusion

  • This defect will be fixed in:
6.0.0 SR9
.
The optimizer has been fixed to compute the length of the
arraycopy correctly.
.
To obtain the fix:
Install build 20101013 or later

Temporary fix
