Comment 2 _ rkubacki 2003-02-25 16:38:28 UTC 
Bad sSynchronization between getPlugin and refreshPlugin?
Comment 3 Petr Jiricka 2003-02-26 10:04:17 UTC 
Yes, this is caused by bad synchronization. This is also 
related to issue 30974, where a similar exception 
occurred, however the fix for 30974 did not fix this 
completely.

Checking in JspDataObject.java;
