The problem appears to be
 -bootclasspath ''
the following argument is not parsed properly.


Setting -bootclasspath to " " produces the same error.

Removing -bootclasspath gives:
1. ERROR in tools/sun/jvmstat/perfdata/monitor/PerfStringMonitor.java (at line 103)
        return new String(b, 0, i, defaultCharset);
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The constructor String(byte[], int, int, Charset) is undefined


Setting -bootclasspath ':' finishes compile, but with warnings:
  incorrect classpath: :
  Annotation processing got disabled, since it requires a 1.6 compliant JVM


Fixing the other appearances of bootclasspath im Makefile, make continues
till compile of OpenJDK(?):

[...]

As ECJ-3.4 help gives default as
    -1.4             + use 1.4 compliance (-source 1.3 -target 1.2)
and call has no option to raise this, this error seems clear.


Now..
1) Is my ECJ good enough?
2) Where to set option to get a higher level (5? 6?) passed properly?


Thanks for any hints,
Martin
