IV90105: JAVA IMPROPERLY REUSES STACK LOCATION
Closed as program error.
Error Message: N/A . Stack Trace: N/A . A local variable or temporary on the stack holds an incorrect value, including possibly a reference to an object of unexpected type, during execution of a method body compiled for profiling.
The problem can be avoided by using -Xjit:disableCompactLocals, at the cost of additional stack usage. If this option is restricted to the problematic method, the increase in stack usage should generally be small.
The JIT compiler performs an analysis in order to share stack space between local variables and temporaries with nonoverlapping lifetimes. When compiling for profiling, further optimization could be performed after this analysis, invalidating the result. In this case, variables with overlapping lifetimes could be assigned the same storage location.
The compiler has been modified to ensure that conflicting variables are assigned distinct stack locations when compiling for profiling. . This APAR will be fixed in the following Java Releases: 7 R1 SR3 FP60 (220.127.116.11) 8 SR3 FP20 (18.104.22.168) 7 SR9 FP60 (22.214.171.124) 6 R1 SR8 FP35 (126.96.36.199) 6 SR16 FP35 (188.8.131.52) .
