https://github.com/eclipse-openj9/openj9/compare/080f0db811...022a2a444e5
Since it seems to be failing in every build, we need to fix it or exclude it asap.
@hzongaro : this seems to be crashing in EA fairly consistently. Could you have a look please?
Status thus far. The immediate cause of the failure is that a call to TR_EscapeAnalysis::fixupNode passes NULL as the parent node, as the node that's being fixed up is a tree top node. In the process of fixing up that node, the parent's opcode is examined, without any guard testing for whether the parent is NULL.

5424 if (fixupNode(node, NULL, visited))
The node in question is an awrtbari. Comments above this block of code indicate that Escape Analysis is handling a case where the operation is writing to a field of a candidate for discontiguous stack allocation and the JIT believes that the field is not a field in the object that's being allocated. Such situations can arise, for instance, if the field access of a subclass is guarded by an instanceof test.
I will need to add a test to fixupNode to guard against the possibility that parent is NULL, but first I'm investigating whether Escape Analysis is correct in thinking that the field that's being written to is not actually in an instance of the class that's being allocated. Things look a bit suspicious, so I'm trying to capture more debug output. In particular, from the jitdump and core file from https://openj9-artifactory.osuosl.org/artifactory/ci-openj9/Test/Test_openjdk21_j9_sanity.openjdk_aarch64_linux_OMR_testList_2/19/openjdk_test_output.tar.gz, the candidate for stack allocation and the field that's written (after the awrtbari has been transformed into an astorei) look like this. The fact that Escape Analysis thinks the arg\$1 field is not part of the lambda that's being allocated seems suspicious, and might be a symptom of another problem that the failure to check whether parent was NULL just happened to trip across.

I went pawing through node n9177n [0xffff49f50440] to see which class was being referenced at that point, as there are seven with that name, some of which have no fields and some of which have an arg$1 field. From jdmpview:

In gdb, at TR_EscapeAnalysis::fixupNode:
(gdb) p candidate->_node->_unionBase._unionedWithChildren._caseInfo._firstChild
$11 = (TR::Node *) 0xffff49f50440
(gdb) p *(TR::StaticSymbol*) candidate->_node->_unionBase._unionedWithChildren._caseInfo._firstChild->_unionPropertyA._symbolReference->_symbol
$14 = {<J9::StaticSymbol> = {<OMR::StaticSymbol> = {<TR::Symbol> = {<J9::Symbol> = {<OMR::Symbol> = {
_vptr.Symbol = 0xffff8abbdae8 <vtable for TR::StaticSymbol+16>, _size = 8, _name = 0x0, _declaredClass = 0x0, _flags = {_flags = 99079},
_flags2 = {_flags = 0}, _localIndex = 65535}, _recognizedField = J9::Symbol::Com_ibm_gpu_Kernel_blockIdxX}, <No data fields>},
_staticAddress = 0xfffee80da800, _assignedTOCIndex = 0}, _callSiteIndex = 0, _classSignature = 0x0, _classSignatureLength = 0,
_isPrimitive = false, _recognizedField = J9::Symbol::UnknownField, _methodTypeIndex = 131072}, <No data fields>}
So the address referenced by the symbol is 0xfffee80da800, which agrees with the content of the Candidate object:
(gdb) p candidate->_class
$18 = (void *) 0xfffee80da800
(gdb) p candidate->_size
$19 = 24
According to both jdmpview and kca, that class has an arg$1 field at offset 16, so I'm not sure how Escape Analysis comes to think that the awrtbari is writing to a field that's not in the object.

The function candidateHasField is responsible for determining whether a field accesses a field that's actually in a candidate. In particular, I'm looking at these lines:
TR_OpaqueClassBlock *fieldClassInCP = fieldSymRef->getOwningMethod(comp)->getClassFromFieldOrStatic(comp, fieldSymRef->getCPIndex());
if ( fieldClassInCP
&& TR_yes == comp->fej9()->isInstanceOf((TR_OpaqueClassBlock*)candidate->_class, fieldClassInCP, true))
From the store node, the owning method index of the field is 277:
n4857n astorei jdk/internal/foreign/abi/AbstractLinker$$Lambda/0x0000000000000000.arg$1 Ljava/lang/foreign/FunctionDescriptor;[#993 final Shadow +16] [flags 0xa0607 0x0 ] () [ 0xffff49debde0] bci=[42,6,-] rc=0 vc=992 vn=2 li=- udi=- nc=2 flg=0x20
(gdb) p *((TR::Node *)0xffff49debde0)->_unionPropertyA._symbolReference
$31 = {<J9::SymbolReference> = {<OMR::SymbolReference> = {_vptr.SymbolReference = 0xffff8abb25d8 <vtable for TR::SymbolReference+16>,

_independentSymRefs = 0x0}}, <No data fields>}, <No data fields>}
The j9method for index 277:
(gdb) p this->_manager->_optimizer->_compilation->_methodSymbols->_array[277]->_methodAddress
$48 = (void *) 0xfffee80da728
(kca) j9method 0xfffee80da728

Notice that the J9Class is 0xfffee80da500, rather than 0xfffee80da800. I'm wondering how we seem to be using an <init> method for a different class. . . .

Henry (@hzongaro), could you post a brief status update on this JDK 21 issue and the outlook for JDK 21 please? Thanks.
I haven't investigated further since last time, but I'll spend some time on it this week. I think I should be able to have a fix ready for JDK 21.
I spent some time producing logs running TestLoaderLookup.java locally, just to see whether the circumstances involving instances of jdk/internal/foreign/abi/AbstractLinker$$Lambda/0x0000000000000000 being allocated and then stored to via a field AbstractLinker$$Lambda/0x0000000000000000.arg$1 that is part of a different class might be seen even without escape analysis attempting to stack allocate it. I found that I did see that situation running with:

I found that before Global Value Propagation, two (amongst several) object allocations being performed through Unsafe.allocateInstance that were then transformed to jitNewObject by Global VP:

The j9class for n6392n is 0x2AD000, while the j9class for n6428n is 0x2AD300. Both awrtbari instructions at n2321n and n2616n, however, use the same field shadow symbol, and when EA queries which class owns that field it gets back 0x2AD000, which it finds is not an instance of the j9class 0x2AD300.
Using the fix in #18374, 100X Grinder of TestLoaderLookup.java and 100X Grinder running jdk_foreign_0 all passed.
The problem with recognizing whether fields in hidden classes are the same was fixed by pull request #18374. That bug resulted in trees that expose the latent bug in Escape Analysis that resulted in the crash first reported in this issue. That latent bug is still present, so I will leave this issue open until that bug is fixed, but I will move this issue to release-0.44, as it's unlikely to be seen.
Closing this issue. The bug that ultimately caused the test failure was fixed under pull request #18374. The latent bug in Escape Analysis described in a comment above will be tracked under issue #19148.
