Error description
Error Message: An ArrayIndexOutOfBoundsException is thrown when attempting to convert a BigDecimal to a String. . Stack Trace: Throwable trace: java.lang.ArrayIndexOutOfBoundsException at java.math.BigInteger.smallToString at java.math.BigInteger.toString at java.math.BigInteger.toString . This issue only happens on z Systems when the JIT is enabled and the specific path is exercised frequently.
Local fix
This issue can be worked around using the -Xjit:disableGRA option. Note however that using this option will degrade performance.
Problem summary
The problem is caused by incorrect handling of sign and zero load extension optimizations in the JIT compiler.
Problem conclusion
The JIT compiler has been updated to correct the handling of load extensions. . This APAR will be fixed in the following Java Releases: 8 SR5 FP10 (8.0.5.10) .
