Error description
Error Message: Unexpected exception thrown: ArrayIndexOutOfBoundsException . Stack Trace: Throwable #1: java.lang.ArrayIndexOutOfBoundsException at __randomizedtesting.SeedInfo.seed(<OSB>831619B333C362E6:B6EC6414 93EA4AD3<CSB>:0) at org.apache.lucene.uninverting.DocTermOrds$OrdWrappedTermsEnum.se ekCeil(DocTermOrds.java:692) at org.apache.lucene.uninverting.TestFieldCacheVsDocValues.assertEq uals(TestFieldCacheVsDocValues.java:570) at org.apache.lucene.uninverting.TestFieldCacheVsDocValues.assertEq uals(TestFieldCacheVsDocValues.java:511) at org.apache.lucene.uninverting.TestFieldCacheVsDocValues.doTestSo rtedSetVsUninvertedField(TestFieldCacheVsDocValues.java:396) at org.apache.lucene.uninverting.TestFieldCacheVsDocValues.testSort edSetFixedLengthVsUninvertedField(TestFieldCacheVsDocValues.java :105) at java.lang.Thread.run(Thread.java:785) . Occurs on x86 processors only.
Local fix
If the stack trace matches exactly, this workaround will work: -Xjit:exclude={*OrdWrappedTermsEnum.seekCeil*} Otherwise, you'd have to know which method is encountering this problem and exclude it.
Problem summary
The jit compiler performed an erroneous transformation when it encountered code of the following equivalent forms: if (?variable == 0) ... or if (variable ? -1 == 0) ... The compiler can implement the bitwise complement operation "?" using the x86 "not" instruction. Under certain circumstances, the compiler would erroneously implement the "if" branch using an instruction that checks the condition codes generated by the "not" instruction, but the "not" instruction does not set the condition codes, and so the branch may not occur at the correct times when the resulting code is executed.
Problem conclusion
The jit compiler was modified to ensure that correct test and branch instructions are generated for this scenario. . This APAR will be fixed in the following Java Releases: 8 SR1 FP10 (8.0.1.10) .
