Description
|
Test execution results are erroneous when C2 with -Xcomp is used.
-Xint / -client / -server -Xmixed:
[
Tester.var_29 = 2.6356778E38
Tester.var_28 = true
]
-server -Xcomp:
[
Tester.var_29 = 98.0
Tester.var_28 = true
]
I observe such behavior at least on linux-x86/x64 with both JDK 6u10b11 and JDK 7b24.
Testcase is attached.

A compiled method misses throwing a NegativeArraySizeException.

The bug only occurs when allocating a multi-dimensional array where the lowest dimension has negative size, all of the higher dimension sizes are constants, and at least one of those higher dimension sizes is zero.
The fix to bug 6603492 tries to optimize some cases of multidimensional array allocations. It fails to cause the NegativeArraySizeException to be thrown when a dimension size is zero.
