[rules-users] drools compiler error

Hi, I am using drools version 3.2 with JANINO compiler. I have an application that processes about 30k rules. Most of the time it works fine but sometime (1 in 20), I get this error. 2007-11-10 02:15:20,658 ERROR [STDERR] java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem; 2007-11-10 02:15:20,658 ERROR [STDERR] at org.apache.commons.jci.compilers.EclipseJavaCompiler$2.acceptResult(EclipseJavaCompiler.java:237) 2007-11-10 02:15:20,658 ERROR [STDERR] at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:335) 2007-11-10 02:15:20,658 ERROR [STDERR] at org.apache.commons.jci.compilers.EclipseJavaCompiler.compile(EclipseJavaCompiler.java:268) 2007-11-10 02:15:20,658 ERROR [STDERR] at org.drools.compiler.PackageBuilder.compileAll(Unknown Source) 2007-11-10 02:15:20,658 ERROR [STDERR] at org.drools.compiler.PackageBuilder.addPackage(Unknown Source) 2007-11-10 02:15:20,658 ERROR [STDERR] at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) thanks, Prashant
