      Description

      OPERATING SYSTEM(S):
      =======================
      Linux and Windows.

      FULL JDK VERSION(S):
      =======================
      java version "1.6.0_01"
      Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
      Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode)

      DESCRIPTION:
      ======================
      javac compile errors while autoboxing a Boolean/Integer.
      while autoboxing a Boolean javac throws Fatal Error: Unable to find method booleanValue.

      The same is true for Integer, javac throws Fatal Error: Unable to find method intValue.

      I'm seeing javac compile errors that seem to be related to the use of autoboxing.

      For example, when autoboxing a Boolean, I get this error:

          [javac] /extra/JDK6_BUILD/WEB/ws/build/build2/Test.java:6: cannot find symbol
          [javac] symbol : method booleanValue()
          [javac] location: class java.lang.Boolean
          [javac] boolean b = (Boolean) o[1];
          [javac] ^
          [javac] Fatal Error: Unable to find method booleanValue

      And when autoboxing an Integer, I get this error,

          [javac] location: class java.lang.Integer
          [javac] int i = (Integer) o[1];
          [javac] ^
          [javac] Fatal Error: Unable to find method intValue

      This only seems to happen when there is more than one javac process running in parallel, which we do in our build environment.

      Recreation Steps:
      =================
      There is a tool created for recreating the problem. The tool generates the source files for however many threads are desired and then compiles them simultaneously.

      The tool can be downloaded from here:
