Created attachment 287907 [details] sample code causing problem Noticed while experimenting with custom preview contents in the formatter settings window. After pasting some invalid code with switch statements (see attached source.java), StackOverflowError occurred. I'll attach the full logs in a separate file, here's a repeating fragment of the stacktrace: at org.eclipse.jdt.internal.compiler.parser.Scanner.disambiguateYieldWithLookAhead(Scanner.java:5227) at org.eclipse.jdt.internal.compiler.parser.Scanner.disambiguatedRestrictedIdentifierYield(Scanner.java:5318) at org.eclipse.jdt.internal.compiler.parser.Scanner.internalScanIdentifierOrKeyword(Scanner.java:3905) at org.eclipse.jdt.internal.compiler.parser.Scanner.scanIdentifierOrKeyword(Scanner.java:3228) at org.eclipse.jdt.internal.compiler.parser.Scanner.getNextToken0(Scanner.java:1967) at org.eclipse.jdt.internal.compiler.parser.Scanner.getNextToken(Scanner.java:1407) at org.eclipse.jdt.internal.compiler.parser.Scanner$VanguardParser.parse(Scanner.java:4899) at org.eclipse.jdt.internal.compiler.parser.Scanner$ScanContextDetector.getScanContext(Scanner.java:4985) at org.eclipse.jdt.internal.compiler.parser.Scanner.getScanContext(Scanner.java:3030) at org.eclipse.jdt.internal.compiler.parser.Scanner.resetTo(Scanner.java:3017) at org.eclipse.jdt.internal.compiler.parser.Scanner.resetTo(Scanner.java:2991) at org.eclipse.jdt.internal.compiler.parser.Scanner.resetTo(Scanner.java:2988) at org.eclipse.jdt.internal.compiler.parser.Scanner.disambiguateYieldWithLookAhead(Scanner.java:5227) Turns out the formatter was trying to guess what kind of source was pasted into the preview panel so it invoked the parser with different kinds and the error occurred with K_MODULE_INFO.
