Error description
Error Message: A floating point error is raised by the JIT compiler during method compilation causing the Java Runtime Environment to unexpectedly terminate. . Stack Trace: TR_ResolvedJ9MethodBase::isCold(TR_Compilation*,bool,TR_Resolved MethodSymbol*) TR_J9EstimateCodeSize::realEstimateCodeSize(TR_CallTarget*,TR_Ca llStack*,bool) TR_J9EstimateCodeSize::estimateCodeSize(TR_CallTarget*,TR_CallSt ack*,bool) TR_EstimateCodeSize::calculateCodeSize(TR_CallTarget*,TR_CallSta ck*,bool) TR_InlinerBase::applyPolicyToTargets(TR_CallStack*,TR_CallSite*) TR_InlinerBase::getSymbolAndFindInlineTargets(TR_CallStack*,TR_C allSite*,bool) TR_MultipleCallTargetInliner::walkCallSites(TR_ResolvedMethodSym bol*,TR_CallStack*,TR_Inner...

Local fix
This problem can be avoided by disabling inlining. However, doing that globally is likely to affect performance, so it should only be disabled on the method which the JIT compiler is crashing trying to compile to minimize performance impact using the following Java command line option template: -Xjit:{package/Class.method(signature)}(disableInlining)
Problem summary
The JIT compiler makes calculations which include division as part of its heuristics. In rare cases a value can be zero and a calculation which uses this value as the divisor did not guard against the possibility of the value being zero leading to the possibility of a division by zero error which causes the JRE to crash reporting a Floating Point Error.
Problem conclusion
The JIT compiler has been updated to guard against the value being zero to prevent a division by zero error. . This APAR will be fixed in the following Java Releases: 8 SR4 FP10 (8.0.4.10) 7 R1 SR4 FP10 (7.1.4.10) 6 R1 SR8 FP50 (6.1.8.50) 6 SR16 FP50 (6.0.16.50) 7 SR10 FP10 (7.0.10.10) .
