Error description
The initialization of a JVM in CICS fails with an ABEND 4094 after Java was migrated from 1.4.2 to Java 1.5. The dump showed that a one byte overlay x'00' did happen in the heap storage after a x"448" bytes area which was obtained by the sjpjp_process_system_properties routine in module DFHSJPJP. This area was filled with JVMs classpath. It was determined that the routine in DFHSJPJP that works out the total length of the classpath that is going to be built is 1 byte out. It uses STRLEN to get the lengths of each string that is going to be concatenated. It allows for extra ':' characters to be inserted to make a valid classpath, but it does not allow for the final null.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Attempts to start a Java 5 JVM fail * * with ABENDS ASRA and ASRB. * **************************************************************** * RECOMMENDATION: * **************************************************************** An ASRB ABEND and an ASRA ABEND occurs with attempts to run a Java program. This problem is caused by a 1 byte overlay of a trailing null. The area causing the overlay was obtained by CICS code to construct the classpath to pass to the JVM. The length of the area that was malloc'ed was 1 byte too short. It was the exact length of the data but did not allow for the trailing null character which C code uses to terminate strings. This null had overlaid the following control block and caused the failure. Additional keywords: ABENDASRA ABENDASRB
Problem conclusion
DFHSJPJP has been amended so that the null terminator will be taken into account when the length of the storage to be malloc'ed for the classpath, is calculated.
