com.hazelcast.cp.internal.datastructures.spi.blocking.AbstractBlockingService.heartbeatSession(AbstractBlockingService.java:311)
That's just a string concatenation:
Even concatenating null
doesn't cause a NullPointerException
. I've looked in the openj9
source of StringConcatHelper#stringOf
and don't see any method handle usage so I'm guessing this is some kind of JDK/JIT optimization issue. There's a similar previous issue that validates this feeling.
The full stack trace isn't much more helpful, either:
java.lang.NullPointerException: null
at java.base/java.lang.StringConcatHelper.stringOf(StringConcatHelper.java) ~[?:?]
at com.hazelcast.cp.internal.datastructures.spi.blocking.AbstractBlockingService.heartbeatSession(AbstractBlockingService.java:311) ~[classes/:?]
Closing to see if happens again...
