WebSphere crashes when attempting to use newer versions of Jenkins built on Java 7. We have updated to all the latest patches of WebSphere 8.5.5.5 and to the newly released IBM JDK 1.7.1. IBM Support states they have seen similar things with com4j corruption. Is it possible for you to look into what IBM states?

Here is IBM's last email.

----------
I have found a similar pattern of corruption like in the old PMRs which
was due to the corruption by com4j and its relevant JNI modules.

> j9javavm! | charsfrom !j9portlibrary | run | charsfrom
!j9portlibraryglobaldata | run | grep corruptedMemoryBlock
0x0: void * corruptedMemoryBlock = !j9x 0x0000000022842120

> j9x 0x0000000022842120,50
0x22842120 : 00000000247781f0 0000000018868160 [ ..w$....´....... ]
0x22842130 : 0000455344740000 000000002351fbd8 [ ..tDSE....Q#.... ]
>> 0x22842140 : 0000000000000000 0000000000000020 [ ........ ....... ]
Corruption here.

Can you please check with com4j and its relevant JNI modules to debug
this issue further.
