As an example use the Counter.java and CounterTest.java from
http://www.isr.umd.edu/~austin/ence489c.d/threads.d/Making_A_Thread_Subclass/
o change the new Counter instantiation to use about 40 instead of 5 in
JavaTest.java.
o compile with "javac Counter.java CounterTest.java".
o run "java CounterTest"
o attempt gcore with "gcore -o core <pid of java CounterTest>" )
Results include:
(no debugging symbols found)
...
---Type <return> to continue, or q <return> to quit---
(no debugging symbols found)
...
gcore: failed to create core.31783
A fix for http://sourceware.org/bugzilla/show_bug.cgi?id=9591 would likely
resolve this issue. But a simple workaround for the gcore script resolves the
issue for the gcore case:
