Hi all, I tried to get thread dump via jstack command on CLHSDB. But it was failed as below:
``` Caused by: sun.jvm.hotspot.types.WrongTypeException: field "_stack_traversal_mark" in type nmethod is not of type jlong, but instead of type long at jdk.hotspot.agent/sun.jvm.hotspot.types.basic.BasicType.getField(BasicType.java:206) at jdk.hotspot.agent/sun.jvm.hotspot.types.basic.BasicType.getField(BasicType.java:212) at jdk.hotspot.agent/sun.jvm.hotspot.types.basic.BasicType.getJLongField(BasicType.java:249) at jdk.hotspot.agent/sun.jvm.hotspot.code.NMethod.initialize(NMethod.java:108) at jdk.hotspot.agent/sun.jvm.hotspot.code.NMethod.access$000(NMethod.java:35) at jdk.hotspot.agent/sun.jvm.hotspot.code.NMethod$1.update(NMethod.java:81) at jdk.hotspot.agent/sun.jvm.hotspot.runtime.VM.registerVMInitializedObserver(VM.java:451) at jdk.hotspot.agent/sun.jvm.hotspot.code.NMethod.<clinit>(NMethod.java:79) ... 23 more ``` I think this exception is caused by JDK-8186837. This changeset has changed the type of `nmethod::_stack_traversal_mark` to `long` from `jlong`. SA should follow this change. I uploaded a webrev for this issue. This webrev is generated from consolidated repo (jdk10/master). Could you review it? http://cr.openjdk.java.net/~ysuenaga/JDK-8187597/webrev.00/ I cannot access JPRT. So I need reviewer. Thanks, Yasumasa
