Hi, can somebody please review this tiny fix which only affects the ppc64 platforms: http://cr.openjdk.java.net/~simonis/webrevs/2017/8186667/ https://bugs.openjdk.java.net/browse/JDK-8186667 The fix for JDK-8172020 increased some interpreter entry points (notably the return entry points) considerably because it added special handling for popframe/earlyreturn in cases where debugging is enabled. This was just enough to overflow the current InterpreterCodeSize on AIX/ppc64 which was 230K until now: # Internal Error (interpreter.hpp:105), pid=16449790, tid=258 # guarantee(codelet_size > 0 && (size_t)codelet_size > 2*K) failed: not enough space for interpreter generation Apparently we've only done debugging tests on jdk10 (and not jdk10-hs) so we've only noticed this now after jdk10-hs was integrated into jdk10. As solution I propose to set InterpreterCodeSize to 256K on ppc64 to be on the safe side again. Thank you and best regards, Volker
