A DESCRIPTION OF THE PROBLEM :
When TlsAlloc() is called successfully for 64 or more times to allocate 64 thread local storage slots and JNI_CreateJavaVM is then used to initialize the jrockit JVM, the initialization fails with the error:
[ERROR] Could not find allocated thread local data key in TIB.
[ERROR] Could not create Fast TLD.
JRockit aborted: Unspecified error (52)

The reason is because within the jvm.dll, TlsAlloc is first called to allocate a new TLS slot and then subsequently, TLSSetValue is called to set the TLS slot to a value 4711. A pointer is then used to iterate through from the start of the thread environment/information block(TEB/TIB) 4 bytes at a time until 8192 bytes past the start of the TEB/TIB. If it fails to find 4711 within this range of bytes, then the error above occurs. However, because windows only has space in the TEB/TIB for 64 TLS slots, any more slots allocated would be stored in a list pointed to by a pointer in the TEB/TIB called TlsExpansionSlots as stated in:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms686708%28v=vs.85%29.aspx
Hence, the logic in the jvm.dll would not be able to find value set in the TLS slot within the TEB/TIB itself unless it follows the TlsExpansionSlots pointer to the list.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In a C program,
Allocate 64 TLS slots by calling TLSAlloc() 64 times successfully
Call JNI_CreateJavaVM to initialize the jrockit JVM

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -

[ERROR] Could not find allocated thread local data key in TIB.
[ERROR] Could not create Fast TLD.
JRockit aborted: Unspecified error (52)
ACTUAL -

[ERROR] Could not find allocated thread local data key in TIB.
[ERROR] Could not create Fast TLD.
JRockit aborted: Unspecified error (52)

ERROR MESSAGES/STACK TRACES THAT OCCUR :

[ERROR] Could not find allocated thread local data key in TIB.
[ERROR] Could not create Fast TLD.
JRockit aborted: Unspecified error (52)

REPRODUCIBILITY :
This bug can be reproduced always.
