PK72606: ECLIPSE JDT COMPILER OPTIONS RETRIEVED DURING THE WORKSPACEBUILD ANT TASK MAY BE NULL SO SHOULD NOT BE SAVED DURING CLEANUP

Rational Application Developer for WebSphere Software, Version 7.0.0.8
6.1.1.8: WebSphere Application Server Toolkit Version 6.1.1 Fix Pack 8

APAR status

• Closed as program error.

Error description

• The WorkspaceBuild J2EE Ant task retrieves 3 JDT (Java compiler)
  options which may be disabled with a value of 'null'.
  The Ant task changes these values depending on the
  DebugCompilation attribute value and then reverts them
  to their original value on clean-up.
  If the original value is 'null' then they should not be saved in
  the underlying Hashtable that the Eclipse JDT uses to store the
  values.

  * PROBLEM DESCRIPTION: A NullPointerException may happen       *
  *                      when using the WorkspaceBuild Java 2    *
  *                      Platform Enterprise Edition (J2EE)      *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The following NullPointerException may happen during execution
  of the WorkspaceBuild J2EE Ant Task:
  
  java.lang.NullPointerException
   at java.util.Hashtable.put(Hashtable.java:632)
   at
  com.ibm.etools.ant.extras.WorkspaceBuild.restoreDebugOptions(Wor
  kspaceBuild.java:155)
   at
  com.ibm.etools.ant.extras.WorkspaceBuild.execute(WorkspaceBuild.
  java:94)
  
  The underlying Java compiler uses a Hashtable to store the
  preferences.  In this scenario we are attempting to store a
  'null' value into this Hashtable which results in the
  NullPointerException.
  

Problem conclusion

• A null check has been added to ensure that 'null' values are
  not added to the Java compilers hashtable of options.
  
  The fix for this APAR is currently targeted for inclusion in
  the WebSphere Application Server Toolkit fixpack 6.1.1.8. and
  Rational Application Developer fixpack 7.0.0.8.  Please refer
