[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - JBAS-4960 - broken merge

[adrian@jboss.org]

With the latest change to the JBossWebMetaData, the merge is failing
due to an NPE.


  | Caused by: java.lang.NullPointerException
  |         at org.jboss.metadata.web.jboss.JBossWebMetaData.merge(JBossWebMetaData.java:1051)
  |         at org.jboss.metadata.web.jboss.JBossWebMetaData.merge(JBossWebMetaData.java:871)

  |         ... 18 more

This is caused by the change in maxActiveSessions:

  | -   private int maxActiveSessions = -1;
  | +   private Integer maxActiveSessions = null;
  | 

breaking this code (line 1051 is the if statement):

  |       if(override != null && override.maxActiveSessions != -1)
  |          setMaxActiveSession(override.maxActiveSessions);
