EVALUATION Name: dd4877 Date: 07/29/2004 daniel.daugherty@Sun 2004-07-29 JVM/TI error 62 is JVMTI_ERROR_FAILS_VERIFICATION. Here is the e-mail on the topic from Robert: >From Robert Field Date: 07/19/2004 08:26 PM Subject: Re: Error ID 62: Class bytes fail verification > It is not OK -- a bug should be sbmitted. Obviously not a showstopper. > Did it run out of memory? It's not filling memory, The machine has 16G memory. Also I tried it on windows and linux.All the platforms at about 24000 iterations this failure happens. ====================================================================== ###@###.### 2004-07-29 ###@###.### 2004-07-29 Not likely to be encountered by a customer. BEGIN::###@###.### 2004-08-12 See the comments section for evaluation information. In this case it is running out of memory with repeated redefine. So fix for this is to return a out of memory error instead of class verification failure error. END::###@###.### 2004-08-12
