Unrecognized character confuses the parser

[fcostasilva]

Just by chance I tried to parse a Java code with a block comment with the MIT License. My name was encoded as Fábio, instead of Fábio and for some reason this seems to cause several problems to the parser. Next I put a simple source code along with the raised exception:

Code:

/*
 * Copyright 2017 Fábio
 */
package myPackage;

import java.time.LocalDateTime;

public class MyClass {

}

Exception:

java.lang.StringIndexOutOfBoundsException: String index out of range: -10 at java.lang.String.substring(String.java:1931) at com.netflix.rewrite.parse.OracleJdkParserVisitor.visitCompilationUnit(OracleJdkParserVisitor.kt:311) at com.netflix.rewrite.parse.OracleJdkParserVisitor.visitCompilationUnit(OracleJdkParserVisitor.kt:40) at com.sun.tools.javac.tree.JCTree$JCCompilationUnit.accept(JCTree.java:550) at com.sun.source.util.TreePathScanner.scan(TreePathScanner.java:68) at com.netflix.rewrite.parse.OracleJdkParser.parse(OracleJdkParser.kt:112) at com.netflix.rewrite.parse.AbstractParser.parse(Parser.kt:69) at com.netflix.rewrite.parse.Parser$DefaultImpls.parse(Parser.kt:58) at com.netflix.rewrite.parse.AbstractParser.parse(Parser.kt:65) at myPackage.MyTest.parse(MyTest.java:61) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:678) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)
