IV68110: JAVA 7 MULTI-TYPE EXCEPTION CATCH FAILS TO EXECUTE THE FINALLY B LOCK

APAR status

• Closed as program error.

Error description

• Error Message: In a JIT-compiled Java method, a finally block is
  not executed when:
  
  1. A multi-type catch block is used to catch more than one type
  of exceptions.
  
  2. An exception is thrown from the try block that matches
  anything but the first type in the multi-type catch.
  
  3. An exception is thrown from the catch block. It can be a new
  exception, or the caught (re-thrown) exception.
  
  Stack Trace: N/A
  .
  

Local fix

• The issue can be avoided by rewriting the multi-type catch block
  into traditional single-type catch blocks. If it is not feasible
  to rewrite the code, the JIT compiler can be disabled with the
  -Xint option.
  

Problem summary

• The JIT compiler incorrectly processes multi-catch blocks that
  are themselves inside a try region (or have finally clauses,
  which are the same internally).  An internal data structure
  neglects to record the proper control flow information for the
  second and subsequent catch types listed.
  

Problem conclusion

• The JIT compiler has been fixed to generate correct control flow
  for multi-type catch blocks.
