With either eclipse 3.0.0 and 3.0.1 (linux gtk) and Sun JDK 1.4.2_04 and 1.4.2._05 on a stock Mandrake 10.1 (kernel 2.6.8.1-10mdk) debugging an eclipse runtime workbench very often results in both debugged and debuggee processes hanging. This happens after a breakpoint is hit, either on F6 stepping or on double clicking on the class stack in the debug view to open a source editor on another point along the stack. FYI, gtk+ libraries versions I have installed: libgtk+-x11-2.0_0:libgtk+-x11-2.0_0-2.4.9-4mdk.i586.rpm libgtk+2.0_0:libgtk+2.0_0-2.4.9-4mdk.i586.rpm gtk+2.0:gtk+2.0-2.4.9-4mdk.i586.rpm libgtk+1.2:libgtk+1.2-1.2.10-40mdk.i586.rpm libgtk+2.0_0-devel:libgtk+2.0_0-devel-2.4.9-4mdk.i586.rpm libgtk+1.2-devel:libgtk+1.2-devel-1.2.10-40mdk.i586.rpm gtk+licq-base:gtk+licq-base-0.51-12mdk.i586.rpm gtk+licq:gtk+licq-0.51-12mdk.i586.rpm gtk+licq-nognome:gtk+licq-nognome-0.51-12mdk.i586.rpm libgtk+extra0:libgtk+extra0-0.99.17-4mdk.i586.rpm libgtk+extra0-devel:libgtk+extra0-devel-0.99.17-4mdk.i586.rpm
tried also using build I20040907 of the 3.1 stream running on jdk 150rc against a 300 workbench using jdk142_05 : still hangs. this is the host eclipse stack trace (I am unable to do that on the runtime workbench as that is captured by the host which is hung) Full thread dump Java HotSpot(TM) Client VM (1.5.0-rc-b63 mixed mode, sharing): "org.eclipse.jdt.debug: JDI Event Dispatcher" prio=1 tid=0x08962e18 nid=0x1eff in Object.wait() [0x486d9000..0x486d9710] at java.lang.Object.wait(Native Method) -

Moving to SWT for comment. The main thread is in "wait for clipboard contents".
I must add that I was debugging the execution of the 'CUT' action. That's why the clipboard showed up in the thread dump I guess
I installed another distro (Yoper 2.1) which also comes with a 2.8.1 kernel and some 2.4.x GTK+ and the debugger hangs exactly like in mandrake this bug is starting to impact in my time-down-the drain :(
In X, the clipboard is distributed: when you hit paste (or ask if there is anything to paste), the application must send a message to the application that currently holds the clipboard and wait until it responds to get the result. If you cut/copy some text in a process you are debugging, then Eclipse will hang if it ever has to ask for the clipboard contents. See bug 44915 comment #43. Is this what is happening for you?
I was debugging the execution of the CUT action in the Java editor (which eventually led me to open bug 75222). I can't see why the debugger would ever ask for the clipboard content while stepping. anyway the hanging happens specifically here: [code] package org.eclipse.jface.text.source.projection; class ProjectionViewer ...{ ... public void doOperation(int operation) { ... case CUT: ... copyToClipboard(selection.x, selection.y, true, textWidget); ... } [/code] when stepping inside copyToClipboard(..) you'll encounter a line: [code] if (delete) deleteTextRange(offset, length, textWidget); [/code] pressing f5 to step *into* deleteTextRange the debugger hangs. I have just tried this again using 31M2 running on jdk15rc as debugger and the target platform for plugin development is 301 running on jdk142_05
