Bug 356018

Description Tadas 2011-08-28 06:10:27 EDT

Build Identifier: 20110818-2043

Eclipse's default incremental compiler generates invalid bytecode when using 1.7 source and 1.7 target compliance. Default & only Installed JRE in eclipse is jdk1.7.0. Path contains JDK7 binaries, as can be seen:
java -server -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Server VM (build 21.0-b17, mixed mode)

The error that occurs is:
Exception in thread "main" java.lang.VerifyError: Stack map does not match the one at exception handler 74 in method Conformance.main([Ljava/lang/String;)V at offset 4
	at java.lang.Class.getDeclaredMethods0(Native Method)
	at java.lang.Class.privateGetDeclaredMethods(Class.java:2442)
	at java.lang.Class.getMethod0(Class.java:2685)
	at java.lang.Class.getMethod(Class.java:1620)
	at sun.launcher.LauncherHelper.getMainMethod(LauncherHelper.java:484)
	at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:476)

This error does not occur if compiled using javac.
This error does not occur if changed to:
String line = null;

Reproducible: Always

Steps to Reproduce:
Bad bytecode is generated for:

String line;
try (BufferedReader br = new BufferedReader(new InputStreamReader(System.in))) {
	while ((line = br.readLine()) != null)
		if ("exit".equals(line))
			break;
} catch (Exception e) {
	// do anything or nothing
}
