metatech updated FELIX-4527:
----------------------------
Description:
When a bundle is undeployed when ServiceMix is stopped, on the next restart the
FelixStartLevel thread enters an infinite loop.
{code}
"FelixStartLevel" daemon prio=6 tid=0x0000000007ae9800 nid=0x2da4 runnable
[0x00000000091cf000]
java.lang.Thread.State: RUNNABLE
at java.lang.IllegalStateException.<init>(IllegalStateException.java:55)
at org.apache.felix.framework.Felix.acquireBundleLock(Felix.java:4955)
- locked <0x00000000c11bbc88> (a [Ljava.lang.Object;)
at org.apache.felix.framework.Felix.setActiveStartLevel(Felix.java:1156)
at
org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:266)
at java.lang.Thread.run(Thread.java:744)
{code}
This is a side-effect of change FELIX-2942, in which the "for" loop has been
replaced by a "while" loop on a boolean "bundlesRemaining". The
"bundlesRemaining" is not recomputed in every iteration the loop. For instance,
when a IllegalStateException is caught, it skips to the next iteration of the
loop ("continue"). It therefore loops infinitely.
Suggestion solution : recompute the boolean "bundlesRemaining" at each
iteration of the loop (perhaps in a "finally" block ?).
This regression has been introduced in Felix 3.2.x : version 3.0.x did not have
this problem.
The impact on ServiceMix users is that "cold undeploy" is broken, but
fortunately, "warm undeploy" is not.
