In Hawtio console messages viewed in Queue Browser differ based on changing of prioritizedMessages

Issue

• Why removing messages in queue browser, maxBrowsePageSize is not paged in ?

• Following is the setup to see the behaviour:

  • Set the "maxBrowsePage=500"
  • Fill queue with 520 messages
  • Action: delete certain messages via operation 'Remove matching messages(java.lang.string)'
  • Expectation: after deleting x messages, the same number of messages is paged in as replacement for the deleted ones, in sum 500 are shown again

• Testcase 1: messages 1 to 500 are shwon, delete messages 499 and 500 with expression 'JMSXGroupSeq between 499 and 500' (or other criteria matching the last 2 messages paged in) --> confirmation the two messages are deleted, now 501 and 502 are shown/were paged in to fill up to the limit of 500 again --> OK

• Testcase 2: messages 1 to 500 are shwon, delete messages with 'JMSXGroupSeq between 499 and 501' (that means two message paged/499+500 and one message not paged in/501) --> confirmation the three messages are deleted (499,500,501), but only the two new ones 502 and 503 are shown, but not as expected 504 as the third message --> NOT ok

• This effect multiplicates with further deletions of messages increasing the gap between maxBrowsePageSize and the number of messages actually displayed, the more you delete the less are shown afterwards.
