Local fix
Problem summary
Hprof internally uses a function which uses %x as format specifier and hence used %% in order to differentiate it from the regular format specifier. However, the function was later modified to use another function which do not use %x as format specifier and hence %% was treated as the regular text.
Problem conclusion
The JDK has been updated to avoid the duplicate % in the Hprof output. . This APAR will be fixed in the following Java Releases: 8 SR3 FP12 (8.0.3.12) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
