Error description
Error Message: Under rare circumstances a java.lang.NumberFormatException is thrown when deserializing a numeric string that was previously serialized using String.getBytes() with the encoding set to UTF16 on in Java 8 SR2 on POWER8 Little Endian machines only. This problem does not effect Java on AIX, the problem can only occur on little endian LinuxPPC running on POWER8 CPUs. . Stack Trace: N/A .
Local fix
The issue can be worked around by disabling the UTF16 to byte SIMD converters: -Xjit:disableSIMDUTF16BEEncoder,disableSIMDUTF16LEEncoder.
Problem summary
The problem is caused when the SIMD UTF16 to byte encoder introduced in Java 8 SR2 is used to convert a string to bytes on a Little Endian PowerPC 8 system. Bad data is produced in rare circumstances, leading to a variety of potential exceptions when the data is subsequently used. The problem appears in both 32/64 bit SDKs and both default and compressed refs.
Problem conclusion
The defect has been corrected. . This APAR will be fixed in the following Java Releases: 8 SR3 (8.0.3.0) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
