Local fix
If the JVM is not launched with -Xshareclasses option then unset the system property "com.ibm.oti.shared.enabled", (or) Launch the JVM with shared class cache by adding -Xshareclasses option.
Problem summary
The problem is caused when the system property "com.ibm.oti.shared.enabled" is set to "true" but the JVM is not configured to run with shared class cache i.e. JVM is launched without -Xshareclasses option.
Problem conclusion
The JVM has been updated to avoid using system property "com.ibm.oti.shared.enabled" to determine if it is configured to use shared class cache or not. . This APAR will be fixed in the following Java Releases: 7 SR9 (7.0.9.0) 8 SR1 (8.0.1.0) 6 R1 SR8 FP4 (6.1.8.4) 7 R1 SR3 (7.1.3.0) 6 SR16 FP4 (6.0.16.4) .
