Hi,
Is there any way to see how Eclipse calls the compiler?
When I compile/run with Eclipse on Java 1.7 target I got the following exception:
java.lang.VerifyError: JVMVRFY012 stack shape inconsistentIn my IDE, I use the Java 1.7.0_4 release. When I compile it on the command line with javac it works fine. Also if I change the target release to 1.6 it also works fine. I already saw some issues with “stack shape inconsistent” on the eclipse site but I don’t get it. I thought Eclipse internally just calls javac but apparently this isn’t the case.
A test case is simple:
package com.tdv; import java.io.IOException; import java.nio.CharBuffer; public class Java7Test { public static void main(String[] args) { CharBuffer cbuf = CharBuffer.allocate(100); cbuf.append("TEST"); try { Java7Printer.print(cbuf); } catch (IOException e) { e.printStackTrace(); } } }package com.tdv; import java.io.IOException; import java.nio.CharBuffer; public class Java7Printer { protected static String print(CharBuffer buf) throws IOException { try { System.out.println("TEST"); } catch(Exception e) { throw new IOException("ERROR OCCURED"); } return "RETURN_VALUE"; } protected static String decode(CharBuffer buf) { char ch, chc; boolean escaping = false; StringBuffer sb = new StringBuffer(); boolean done = false; do { ch = buf.get(); if (escaping) { switch (ch) { case '\n': do { chc = buf.get(); } while ( (chc == '\r') || (chc == '\n') ); buf.position ( buf.position() - 1 ); break; default: } } else { switch (ch) { case '\r': break; default: } } done = true; } while (!done); return sb.toString(); } }tdevos,
Sorry that you are seeing this issue. This looks like a base Eclipse issue as per this bug report :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=3610531. Can you please copy paste the Installation Details from MyEclipse > Installation Summary > Installation Details ?
2. If you are working with MyEclipse 10.1 , can you please download MyEclipse 10.5 the latest version and check if the issue persists ?
You can install 10.5 alongside your existing installation without deleting it. The license you hold is valid for 10.5 too as our licenses are time based.You can download the MyEclipse 10.5 from here :
http://myeclipseide.com/index.php?name=Recommend_Us&req=Download&version=MELet us know how it works for you.
Hi,
Thanks for looking at this issue. I also found the bug report you indicated but it says at the bottom comment that it was fixed for 3.7.2 RC2.
I use the latest MyEclipse 10.5 which uses Eclipse 3.7.2 final so I thought it was not an issue.
The installation summary is as follows:

Doesn’t it use javac behind the scenes or does it use its own compiler?

tdevos,
I could replicate the issue at my end on Eclipse 3.7.2 IDE for Java EE.
Regarding the question about using the javac, Eclipse uses the java compiler to compile the source but I think it uses an internal validator for on the fly validation. However, it may call it through a method call, rather than the javac executable.
I suggest you raise a bug against Eclipse and check on Eclipse forums about this issue.
Hope it helps.
