IV34696: PERFORMANCE REGRESSION IN CHARACTER CONVERSION AFTER APPLYING APAR IV29910
Closed as program error.
Error Message: More time spent in java.io character conversion routines such as sun.io.CharToByteASCII.convert . Stack Trace: N/A . N/A
A fix for an earlier bug made the jit compiler more conservative, causing it to miss a valid optimization opportunity in the conversion routines during induction variable analysis.
This defect will be fixed in: 7.0.0 SR4 6.0.1 SR5 . The jit compiler's induction variable analysis was improved to find the optimization opportunity that restored character conversion performance.
