Description
Attr.PostAttrAnalyzer is supposed to detect and fill in null values in a partially attributed tree resulting from Attr errors.   It misses the operator field in a JCAssignop tree.
Comments
EVALUATION Ooops. Does not affect batch mode javac, but can affect downstream clients (such as NetBeans) that set the compilePolicy beyond the default value.

SUGGESTED FIX Add the following method to PostAttrAnalyzer @Override public void visitAssignop(JCAssignOp that) { if (that.operator == null) that.operator = new OperatorSymbol(names.empty, syms.unknownType, -1, syms.noSymbol); super.visitAssignop(that); }
