IV12626: FAILS TO OPEN ENCRYPTED DOCUMENTS USING APACHE POI

APAR status

• Closed as program error.

Error description

• Error Message: An EncryptedDocumentException is received while a
  Java 6.0.1 or Java 7 application uses the org.apache.poi API to
  process encrypted documents.
  .

Local fix

• This issue can be avoided using the
  -Xjit:disableRematerialization option. Note that this might
  cause a minor impact on the application's performance.
  

Problem summary

• The problem is caused when the JIT compiler incorrectly
  optimizes a method which both reads and writes from a byte
  array. The resulting compiled code performs an invalid read
  after the byte array has been modified, leading to incorrect
  behaviour.
  

Problem conclusion

• This defect will be fixed in:
  6.0.1 SR1 FP1
  7.0.0 SR1
  .
  The JIT compiler has been updated to eliminate the problematic
  code transformation.
  

Temporary fix
