Local fix
No workaround
Problem summary
JIT compiler did not generate instruction to reload DSA into GPR4 before calling out double remainder helper function, and ended up calling helper with garbage value in GPR4 where segmentation error occurs while accessing memory at GPR4.
Problem conclusion
This JDK has been updated to set proper value in GPR4 before calling remainder helper function. . This APAR will be fixed in the following Java Releases: 8 SR5 FP5 (8.0.5.5) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs. For those running stand-alone, information about the available Service Refreshes and Fix Packs can be found at: https://www.ibm.com/developerworks/java/jdk/
