The error is when one uses the value assigned within a synchronized section, outside of a synchronized section. if(x == null) is outside of synchronized section x = new | method(); Very very specific check for double checked locking. author:    CL Gilbert (dnoyeb@users.sourceforge.net) Method Summary public  String getNameFromPrimaryPrefix(ASTPrimaryPrefix pp)      public  boolean matchName(ASTPrimaryExpression ape, String name)      public  Object visit(ASTMethodDeclaration node, Object data)      public  Object visit(ASTClassDeclaration node, Object data)      public  Object visit(ASTNestedClassDeclaration node, Object data)      public  Object visit(ASTInterfaceDeclaration node, Object data)      public  Object visit(ASTNestedInterfaceDeclaration node, Object data)      Method Detail getNameFromPrimaryPrefix public String getNameFromPrimaryPrefix(ASTPrimaryPrefix pp)(Code) matchName public boolean matchName(ASTPrimaryExpression ape, String name)(Code) visit public Object visit(ASTMethodDeclaration node, Object data)(Code) visit public Object visit(ASTClassDeclaration node, Object data)(Code) visit public Object visit(ASTNestedClassDeclaration node, Object data)(Code) visit public Object visit(ASTInterfaceDeclaration node, Object data)(Code) visit public Object visit(ASTNestedInterfaceDeclaration node, Object data)(Code) Methods inherited from org.acm.seguin.pmd.AbstractRule public void addProperty(String name, String value)(Code)(Java Doc) public void apply(List acus, RuleContext ctx)(Code)(Java Doc) public RuleViolation createRuleViolation(RuleContext ctx, int lineNumber)(Code)(Java Doc) public RuleViolation createRuleViolation(RuleContext ctx, int lineNumber, String specificDescription)(Code)(Java Doc) public boolean equals(Object o)(Code)(Java Doc) public boolean getBooleanProperty(String name)(Code)(Java Doc) public String getDescription()(Code)(Java Doc) public double getDoubleProperty(String name)(Code)(Java Doc) public String getExample()(Code)(Java Doc) public int getIntProperty(String name)(Code)(Java Doc) public String getMessage()(Code)(Java Doc) public String getName()(Code)(Java Doc) public int getPriority()(Code)(Java Doc) public String getPriorityName()(Code)(Java Doc) public RuleProperties getProperties()(Code)(Java Doc) public String getStringProperty(String name)(Code)(Java Doc) public boolean hasProperty(String name)(Code)(Java Doc) public int hashCode()(Code)(Java Doc) public boolean include()(Code)(Java Doc) public void setDescription(String description)(Code)(Java Doc) public void setExample(String example)(Code)(Java Doc) public void setInclude(boolean include)(Code)(Java Doc) public void setMessage(String message)(Code)(Java Doc) public void setName(String name)(Code)(Java Doc) public void setPriority(int priority)(Code)(Java Doc) public Object visit(ASTCompilationUnit expr, Object data)(Code)(Java Doc) protected void visitAll(List acus, RuleContext ctx)(Code)(Java Doc)
