Tobias Mattsson updated JCR-3158:
---------------------------------
Description:
I found a deadlock situation using JR 2.2.10, the problem is with DBCP 1.2.2
and is fixed in DBCP 1.3, JR trunk also uses DBCP 1.2.2 and should also be
updated
The ticket in dbcp is #DBCP-270, related tickets are #DBCP-65 #DBCP-281
#DBCP-271
Stack trace of where my call is stalled:
{code}
main@1, prio=5, in group 'main', status: 'MONITOR'
blocks Timer-1@2545
waiting for Timer-1@2545 to release lock on {1}
