Please help me focus on compiler crash

[Boaz Nahum]

Thanks - It helps a lot.

I was managed to locate the java file that cause the problem and by
elimination the line.

The exception was caused by missing dependency.

The line is:


PostProcessor.registerRequiredReferences(ResultsSaver.getResultsSaverServiceImpl(),

ScanStatisticsCollectorHelper.getStatisticsCollectorServiceImpl(),

SynchWithScanHelper.getProcessingControlServiceImpl());

The problem:

ScanStatisticsCollectorHelper implements DefectsProcessor

I'm compiling unit (Jar) C.
ScanStatisticsCollectorHelper is compiled in unit B
DefectsProcessor is in unit A.

When compiling C, A is not in classpath. And this what caused the
exception. After adding A compilation succeeded.


Also we have exception from the exact same reason:

    [javac]     at com.sun.tools.javac.code.Types.rank(Types.java:3043)
    [javac]     at com.sun.tools.javac.code.Types.rank(Types.java:3015)
    [javac]     at com.sun.tools.javac.code.Types.rank(Types.java:3019)
    [javac]     at com.sun.tools.javac.code.Types.rank(Types.java:3019)
    [javac]     at
com.sun.tools.javac.code.Symbol$TypeSymbol.precedes(Symbol.java:591)


We have many issues like this in JDK 8. C->B->A. In JDK 7 we just add B to
C classpath and it was compiled successfully. In JDK 8 we have 3 different
results:

1. A message  that A cant be found
2. Exception: at com.sun.tools.javac.code.Types.rank(Types.java:3043)
3. Exception: at
com.sun.tools.javac.comp.Flow$FlowAnalyzer.visitApply(Flow.java:1196)

Thank you for your help.
Boaz
