RFR: JDK-8164319: CLHSDB dumpcodecache throws StackOverflowError

[Yasumasa Suenaga]

Hi all,

I encountered StackOverflowError when I run dumpcodecache command in CLHSDB:

------------
hsdb> dumpcodecache
Exception in thread "main" java.lang.StackOverflowError
         at sun.jvm.hotspot.code.CodeBlob.getName(jdk.hotspot.agent at 9-ea/CodeBlob.java:118)
         at sun.jvm.hotspot.code.CodeBlob.getName(jdk.hotspot.agent at 9-ea/CodeBlob.java:118)
         at sun.jvm.hotspot.code.CodeBlob.getName(jdk.hotspot.agent at 9-ea/CodeBlob.java:118)
         at sun.jvm.hotspot.code.CodeBlob.getName(jdk.hotspot.agent at 9-ea/CodeBlob.java:118)
         at sun.jvm.hotspot.code.CodeBlob.getName(jdk.hotspot.agent at 9-ea/CodeBlob.java:118)
             :
------------

CodeBlob#getName() calls itself recursively.
Thus it occurs StackOverflowError.
