Please help me focus on compiler crash (original) (raw)

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

Add

-XDverboseCompilePolicy That should print detailed info about what the compiler is doing (i.e. which file it's compiling before the crash). Maurizio

Because I'm compiling large number of files, I have no way to know which one causes the problem. I added -verbose But it didn't help match (maybe if I send the output it to you ?) Is there any thing I can do to get more information ? Thanks Boaz
