Error description
Error Message: The JVM throws an unexpected NullPointerException from com.ibm.jit.DecimalFormatHelper.formatAsDouble while running some workloads that make use of the BigDecimal class. . Stack Trace: The top frame of the Java backtrace is the method com.ibm.jit.DecimalFormatHelper.formatAsDouble(DecimalFormatHelp er.java:109) .
Local fix
The IBM Java option -Xjit:disableDecimalFormatPeephole is known to correct this issue in all cases. Some workloads may see a small to moderate performance impact when running with this option.
Problem summary
The problem was caused by a JIT compiler optimization responsible for handling patterns of the form DecimalFormat.format(BigDecimal.doubleValue()). This optimization generated incorrect code in some cases.
Problem conclusion
The J9 JIT compiler was modified so that the problematic optimization generates correct code in all cases. . This APAR will be fixed in the following Java Releases: 8 SR3 (8.0.3.0) 7 R1 SR3 FP40 (7.1.3.40) 7 SR9 FP40 (7.0.9.40) 6 R1 SR8 FP25 (6.1.8.25) .
