APAR status
Closed as program error.
Error description
Error Message: A crash is reported in the JIT module when doing cryptographic operations and with an agent attached . Stack Trace: com/ibm/crypto/provider/* . This problem can only occur on x86 and POWER platforms
Local fix
This problem can be avoided by disabling hardware accelerated cryptography using the option -Dcom.ibm.jit.crypto.nohardwarecrypt=true
Problem summary
Java agents can prefix native methods as part of their monitoring functionality via JVMTI. The agent requests control in order to perform its tasks when transitioning from executing Java code to executing native code via JNI. Hardware acceleration of cryptographic functions is implemented using JNI. The JIT re-orders the parameters of certain hardware accelerated methods on certain platforms. When an agent prefixes one of these methods to get control, this parameter re-ordering is no longer valid and thus the parameters of called methods may not be in the right locations which will likely result in a crash.
Problem conclusion
The JIT compiler has been updated to prevent parameter re-ordering of hardware accelerated cryptography methods prefixed by agents. . This APAR will be fixed in the following Java Releases: 8 SR5 FP15 (8.0.5.15) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
