64-bit version of CEE3ERP required

CICS TS 4.2 and above provide support for Java by running a JVM within a 64-bit PIPI enclave (CELQPIPI).

Every thread within the enclave begins life as an LE pthread and so has the LE ESTAE active for error handling. CICS enabled threads will additionally have the CICS ESTAE active ahead of the LE one. The general approach taken by the CICS ESTAE is that all abends are unexpected and it handles everything. This all works fine until an "expected" internal LE abend occurs. The CICS ESTAE catches this abend and handles it by terminating the current in progress request and eventually terminating the entire enclave.

We have seen that for 31-bit PIPI enclaves there is a CEE3ERP interface available that a "vendor" ESTAE routine can call to find out if the abend being processed is really intended for LE or not.

This interface does not appear to have been implemented for 64-bit enclaves.

In order to do error recovery correctly for Java applications in CICS we need a 64-bit interface.
