The crash is reproducible in JDK6 and JDK7. In JDK8 and JDK9 the crash is not reproducible if TieredCompilation flag is set (src/cpu/x86/vm/c2_globals_x86.hpp).

Stacktrace for JDK9 attached.

Fix has been reverted back by # JDK-8040664. New fix was pushed with JDK-8039050

Since we saw issues here, removing critical request. Still keeping critical watch. If we could get this fix out in July, it would be good. Apart from the customer, several Java Incidents have been filed with similar issues, so it seems several users are running into this: JI-7187856 JVM crash at Node::rematerialize() JI-9006526 Java app calling JasperReports 5.0.1 crashes in Eclipse 3.7.2 JI-9005261 JDK7 (inc7u21,7u25) crashes during report export via Jasperreports JI-9004125 A fatal error has been detected by the Java Runtime Environment:

Hot workaround fix for JDK7 and JDK6 will be committed as a temporary solution, Proper fix for JDK8 and JDK9 will be done under the bug JDK-8039050 The temporary fix will introduce a performance regression because loops in next cases will not be converted to Counted and as result will not be unrolled, range check eliminated and some some checks will not be moved from a loop. In other words no loop optimizations will be done for next cases: if (a) { ... } for (; i<l;i++) {} and when head of the loop (back branch target) is bci 0.
